+## Issues
+
+I want to hear about any issues you encounter while using age.
+
+Particularly appreciated are well researched, complete [issues](https://github.com/FiloSottile/age/issues/new/choose) with lots of context, **focusing on the intended outcome and/or use case**. Issues don't have to be just about bugs: if something was hard to figure out or unexpected, please file a **[UX report](https://github.com/FiloSottile/age/discussions/new?category=UX-reports)**! ✨
+
+Not all issue reports might lead to a change, so please don't be offended if yours doesn't, but they are precious datapoints to understand how age could work better in aggregate.
+
+## Pull requests
+
+age is a little unusual in how it is maintained. I like to keep the code style consistent and complexity to a minimum, and going through many iterations of code review is a significant toil on both contributors and maintainers. age is also small enough that such a time investment is unlikely to pay off over ongoing contributions.
+
+Therefore, **be prepared for your change to get reimplemented rather than merged**, and please don't be offended if that happens. PRs are still appreciated as a way to clarify the intended behavior, but are not at all required: prefer focusing on providing detailed context in an issue report instead.
+
+To learn more, please see my [maintenance policy](https://github.com/FiloSottile/FiloSottile/blob/main/maintenance.md).
+
+<!-- ## Feature requests
+
+age is small, simple, and config-free by design. A lot of effort is put into resisting scope creep and enabling use cases by integrating and interoperating well with other projects rather than by adding features.
+
+In particular, I'm unlikely to merge into the main repo anything I don't use myself, as I would not be the best person to maintain it. However, I'm always happy to discuss, learn about, and link to any age-related project! -->
+
+## Other ways to contribute
+
+age itself is not community maintained, but its ecosystem very much is, and that's where a lot of the strength of age is! Here are some ideas for ways to contribute to age and its ecosystem, besides contributing to this repository.
+
+* **Write an article about how to use age for a certain community or use case.** The number one reason people don't use age is because they haven't heard about it and existing tutorials present more complex alternatives.
+* Integrate age into existing projects that might use it, for example replacing legacy alternatives.
+* Build and maintain an [age plugin](https://c2sp.org/age-plugin) for a KMS or platform.
+* Watch the [discussions](https://github.com/FiloSottile/age/discussions) and help other users.
+* Provide bindings in a language or framework that doesn't support age well.
+* Package age for an ecosystem that doesn't have packages yet.
+
+If you build or write something related to age, [let me know](https://github.com/FiloSottile/age/discussions/new?category=general)! 💖

 If the argument to `-R` (or `-i`) is `-`, the file is read from standard input.
 
+### Post-quantum keys
+
+To generate hybrid post-quantum keys, which are secure against future quantum
+computer attacks, use the `-pq` flag with `age-keygen`. This may become the
+default in the future.
+
+Post-quantum identities start with `AGE-SECRET-KEY-PQ-1...` and recipients with
+`age1pq1...`. The recipients are unfortunately ~2000 characters long.
+
+```
+$ age-keygen -pq -o key.txt

+
+Support for post-quantum keys is built into age v1.3.0 and later. Alternatively,
+the `age-plugin-pq` binary can be installed and placed in `$PATH` to add support
+to any version and implementation of age that supports plugins. Recipients will
+work out of the box, while identities will have to be converted to plugin
+identities with `age-plugin-pq -identity`.

+Passphrase-protected identity files are not necessary for most use cases, where access to the encrypted identity file implies access to the whole system. However, they can be useful if the identity file is stored remotely.

+### Inspecting encrypted files
 
-On macOS or Linux, you can use Homebrew:
+The `age-inspect` command can display metadata about an encrypted file without decrypting it, including the recipient types, whether it uses post-quantum encryption, and the payload size.
 
 ```
-brew tap filippo.io/age https://filippo.io/age
-brew install age

+
+const usage = `age-plugin-batchpass is an age plugin that enables non-interactive
+passphrase-based encryption and decryption using environment variables.
+
+WARNING: IN 90% OF CASES, YOU DON'T NEED THIS PLUGIN.
+
+This functionality is not built into the age CLI because most applications
+should use native keys instead of scripting passphrase-based encryption.
+
+Humans are notoriously bad at remembering and generating strong passphrases.
+age uses scrypt to partially mitigate this, which is necessarily very slow.
+
+If a computer will be doing the remembering anyway, you can and should use
+native keys instead. There is no need to manage separate public and private
+keys, you encrypt directly to the private key:
+
+    $ age-keygen -o key.txt
+    $ age -e -i key.txt file.txt > file.txt.age
+    $ age -d -i key.txt file.txt.age > file.txt
+
+Likewise, you can store a native identity string in an environment variable
+or through your CI secrets manager and use it to encrypt and decrypt files
+non-interactively:
+
+    $ export AGE_SECRET=$(age-keygen)
+    $ age -e -i <(echo "$AGE_SECRET") file.txt > file.txt.age
+    $ age -d -i <(echo "$AGE_SECRET") file.txt.age > file.txt
+
+The age CLI also natively supports passphrase-encrypted identity files, so you
+can use that functionality to non-interactively encrypt multiple files such that
+you will be able to decrypt them later by entering the same passphrase:
+
+    $ age-keygen -pq | age -p -o encrypted-identity.txt
+    Public key: age1pq1cd[... 1950 more characters ...]
+    Enter passphrase (leave empty to autogenerate a secure one):
+    age: using autogenerated passphrase "eternal-erase-keen-suffer-fog-exclude-huge-scorpion-escape-scrub"
+    $ age -r age1pq1cd[... 1950 more characters ...] file.txt > file.txt.age
+    $ age -d -i encrypted-identity.txt file.txt.age > file.txt
+    Enter passphrase for identity file "encrypted-identity.txt":
+
+Finally, when using this plugin care should be taken not to let the password be
+persisted in the shell history or leaked to other users on multi-user systems.
+
+Usage:
+
+    $ AGE_PASSPHRASE=password age -e -j batchpass file.txt > file.txt.age
+
+    $ AGE_PASSPHRASE=password age -d -j batchpass file.txt.age > file.txt
+
+Alternatively, you can use AGE_PASSPHRASE_FD to read the passphrase from
+a file descriptor. Trailing newlines are stripped from the file contents.
+
+When encrypting, you can set AGE_PASSPHRASE_WORK_FACTOR to adjust the scrypt
+work factor (between 1 and 30, default 18). Higher values are more secure
+but slower.
+
+When decrypting, you can set AGE_PASSPHRASE_MAX_WORK_FACTOR to limit the
+maximum scrypt work factor accepted (between 1 and 30, default 30). This can
+be used to avoid very slow decryptions.`

+age-inspect(1) -- inspect age(1) encrypted files
+====================================================
+
+## SYNOPSIS
+
+`age-inspect` [`--json`] [<INPUT>]
+
+## DESCRIPTION
+
+`age-inspect` reads an age(1) encrypted file from <INPUT> (or standard input)
+and displays metadata about it without decrypting.
+
+This includes the recipient types, whether it uses post-quantum encryption,
+and a size breakdown of the file components.
+
+## OPTIONS
+
+* `--json`:
+    Output machine-readable JSON instead of human-readable text.
+
+* `--version`:
+    Print the version and exit.
+
+## JSON FORMAT
+
+When `--json` is specified, the output is a JSON object with these fields:
+
+* `version`:
+    The age format version (e.g., `"age-encryption.org/v1"`).
+
+* `postquantum`:
+    Whether the file uses post-quantum encryption: `"yes"`, `"no"`, or
+    `"unknown"`.
+
+* `armor`:
+    Boolean indicating whether the file is ASCII-armored.
+
+* `stanza_types`:
+    Array of recipient stanza type strings (e.g., `["X25519"]` or
+    `["mlkem768x25519"]`).
+
+* `sizes`:
+    Object containing size information in bytes:
+
+    * `header`: Size of the age header.
+    * `armor`: Armor encoding overhead (0 if not armored).
+    * `overhead`: Stream encryption overhead.
+    * `min_payload`, `max_payload`: Payload size bounds (currently always matching).
+    * `min_padding`, `max_padding`: Padding size bounds (currently always 0).
+
+    The fields add up to the total size of the file.
+
+## EXAMPLES
+
+Inspect an encrypted file:
+
+    $ age-inspect secrets.age
+    secrets.age is an age file, version "age-encryption.org/v1".

+age-keygen(1) -- generate age(1) key pairs
+====================================================
+
+## SYNOPSIS
+
+`age-keygen` [`-pq`] [`-o` <OUTPUT>]<br>
+`age-keygen` `-y` [`-o` <OUTPUT>] [<INPUT>]<br>
+
+## DESCRIPTION
+
+`age-keygen` generates a new native age(1) key pair, and outputs the identity to
+standard output or to the <OUTPUT> file. The output includes the public key and
+the current time as comments.
+
+If the output is not going to a terminal, `age-keygen` prints the public key to
+standard error.
+
+## OPTIONS
+
+* `-pq`:
+    Generate a post-quantum hybrid ML-KEM-768 + X25519 key pair.
+
+    In the future, this might become the default.
+
+* `-o`, `--output`=<OUTPUT>:
+    Write the identity to <OUTPUT> instead of standard output.
+
+    If <OUTPUT> already exists, it is not overwritten.
+
+* `-y`:
+    Read an identity file from <INPUT> or from standard input and output the
+    corresponding recipient(s), one per line, with no comments.
+
+* `--version`:
+    Print the version and exit.
+
+## EXAMPLES
+
+Generate a new post-quantum identity:
+
+    $ age-keygen -pq
+    # created: 2025-11-17T13:39:06+01:00
+    # public key: age1pq167[... 1950 more characters ...]
+    AGE-SECRET-KEY-PQ-1K30MYPZAHAXHR22YHH27EGDVLU0QNSUH3DSV7J7NR3X6D9LHXNWSDLTV4T
+
+Generate a new traditional identity:
+
+    $ age-keygen
+    # created: 2021-01-02T15:30:45+01:00
+    # public key: age1lvyvwawkr0mcnnnncaghunadrqkmuf9e6507x9y920xxpp866cnql7dp2z
+    AGE-SECRET-KEY-1N9JEPW6DWJ0ZQUDX63F5A03GX8QUW7PXDE39N8UYF82VZ9PC8UFS3M7XA9

+.SH "DESCRIPTION"
+\fBage\-plugin\-batchpass\fR is an age(1) plugin that enables non\-interactive passphrase\-based encryption and decryption using environment variables\.
+.SH "WARNING"
+This functionality is not built into the age CLI because most applications should use native keys instead of scripting passphrase\-based encryption\.
+.P
+Humans are notoriously bad at remembering and generating strong passphrases\. age uses scrypt to partially mitigate this, which is necessarily very slow\.
+.P
+If a computer will be doing the remembering anyway, you can and should use native keys instead\. There is no need to manage separate public and private keys, you encrypt directly to the private key:
+.IP "" 4
+.nf
+$ age\-keygen \-o key\.txt
+$ age \-e \-i key\.txt file\.txt > file\.txt\.age
+$ age \-d \-i key\.txt file\.txt\.age > file\.txt
+.fi
+.IP "" 0
+.P
+Likewise, you can store a native identity string in an environment variable or through your CI secrets manager and use it to encrypt and decrypt files non\-interactively:
+.IP "" 4
+.nf
+$ export AGE_SECRET=$(age\-keygen)
+$ age \-e \-i <(echo "$AGE_SECRET") file\.txt > file\.txt\.age
+$ age \-d \-i <(echo "$AGE_SECRET") file\.txt\.age > file\.txt
+.fi
+.IP "" 0
+.P
+The age CLI also natively supports passphrase\-encrypted identity files, so you can use that functionality to non\-interactively encrypt multiple files such that you will be able to decrypt them later by entering the same passphrase:
+.IP "" 4
+.nf
+$ age\-keygen \-pq | age \-p \-o encrypted\-identity\.txt
+Public key: age1pq1cd[\|\.\|\.\|\. 1950 more characters \|\.\|\.\|\.]
+Enter passphrase (leave empty to autogenerate a secure one):
+age: using autogenerated passphrase "eternal\-erase\-keen\-suffer\-fog\-exclude\-huge\-scorpion\-escape\-scrub"
+$ age \-r age1pq1cd[\|\.\|\.\|\. 1950 more characters \|\.\|\.\|\.] file\.txt > file\.txt\.age
+$ age \-d \-i encrypted\-identity\.txt file\.txt\.age > file\.txt
+Enter passphrase for identity file "encrypted\-identity\.txt":
+.fi
+.IP "" 0
+.P
+Finally, when using this plugin care should be taken not to let the password be persisted in the shell history or leaked to other users on multi\-user systems\.
+.SH "ENVIRONMENT"
+.TP
+\fBAGE_PASSPHRASE\fR
+The passphrase to use for encryption or decryption\. Mutually exclusive with \fBAGE_PASSPHRASE_FD\fR\.
+.TP
+\fBAGE_PASSPHRASE_FD\fR
+A file descriptor number to read the passphrase from\. Trailing newlines are stripped from the file contents\. Mutually exclusive with \fBAGE_PASSPHRASE\fR\.
+.TP
+\fBAGE_PASSPHRASE_WORK_FACTOR\fR
+The scrypt work factor to use when encrypting\. Must be between 1 and 30\. Default is 18\. Higher values are more secure but slower\.
+.TP
+\fBAGE_PASSPHRASE_MAX_WORK_FACTOR\fR
+The maximum scrypt work factor to accept when decrypting\. Must be between 1 and 30\. Default is 30\. Can be used to avoid very slow decryptions\.

+age-plugin-batchpass(1) -- non-interactive passphrase encryption plugin for age(1)
+==================================================================================
+
+## SYNOPSIS
+
+`age` `-e` `-j` `batchpass`<br>
+`age` `-d` `-j` `batchpass`<br>
+
+## DESCRIPTION
+
+`age-plugin-batchpass` is an age(1) plugin that enables non-interactive
+passphrase-based encryption and decryption using environment variables.
+
+## WARNING
+
+This functionality is not built into the age CLI because most applications
+should use native keys instead of scripting passphrase-based encryption.
+
+Humans are notoriously bad at remembering and generating strong passphrases.
+age uses scrypt to partially mitigate this, which is necessarily very slow.
+
+If a computer will be doing the remembering anyway, you can and should use
+native keys instead. There is no need to manage separate public and private
+keys, you encrypt directly to the private key:
+
+    $ age-keygen -o key.txt
+    $ age -e -i key.txt file.txt > file.txt.age
+    $ age -d -i key.txt file.txt.age > file.txt
+
+Likewise, you can store a native identity string in an environment variable
+or through your CI secrets manager and use it to encrypt and decrypt files
+non-interactively:
+
+    $ export AGE_SECRET=$(age-keygen)
+    $ age -e -i <(echo "$AGE_SECRET") file.txt > file.txt.age
+    $ age -d -i <(echo "$AGE_SECRET") file.txt.age > file.txt
+
+The age CLI also natively supports passphrase-encrypted identity files, so you
+can use that functionality to non-interactively encrypt multiple files such that
+you will be able to decrypt them later by entering the same passphrase:
+
+    $ age-keygen -pq | age -p -o encrypted-identity.txt
+    Public key: age1pq1cd[... 1950 more characters ...]
+    Enter passphrase (leave empty to autogenerate a secure one):
+    age: using autogenerated passphrase "eternal-erase-keen-suffer-fog-exclude-huge-scorpion-escape-scrub"
+    $ age -r age1pq1cd[... 1950 more characters ...] file.txt > file.txt.age
+    $ age -d -i encrypted-identity.txt file.txt.age > file.txt
+    Enter passphrase for identity file "encrypted-identity.txt":
+
+Finally, when using this plugin care should be taken not to let the password be
+persisted in the shell history or leaked to other users on multi-user systems.
+
+## ENVIRONMENT
+
+* `AGE_PASSPHRASE`:
+    The passphrase to use for encryption or decryption.
+    Mutually exclusive with `AGE_PASSPHRASE_FD`.
+
+* `AGE_PASSPHRASE_FD`:
+    A file descriptor number to read the passphrase from.
+    Trailing newlines are stripped from the file contents.
+    Mutually exclusive with `AGE_PASSPHRASE`.
+
+* `AGE_PASSPHRASE_WORK_FACTOR`:
+    The scrypt work factor to use when encrypting.
+    Must be between 1 and 30. Default is 18.
+    Higher values are more secure but slower.
+
+* `AGE_PASSPHRASE_MAX_WORK_FACTOR`:
+    The maximum scrypt work factor to accept when decrypting.
+    Must be between 1 and 30. Default is 30.
+    Can be used to avoid very slow decryptions.
+
+## EXAMPLES
+
+Encrypt a file with a passphrase:
+
+    $ AGE_PASSPHRASE=secret age -e -j batchpass file.txt > file.txt.age
+
+Decrypt a file with a passphrase:
+
+    $ AGE_PASSPHRASE=secret age -d -j batchpass file.txt.age > file.txt
+
+Read the passphrase from a file descriptor:
+
+    $ AGE_PASSPHRASE_FD=3 age -e -j batchpass file.txt 3< passphrase.txt > file.txt.age

+\fBage\fR \- simple, modern, and secure file encryption
+.SH "SYNOPSIS"
+\fBage\fR [\fB\-\-encrypt\fR] (\fB\-r\fR \fIRECIPIENT\fR | \fB\-R\fR \fIPATH\fR)\|\.\|\.\|\. [\fB\-\-armor\fR] [\fB\-o\fR \fIOUTPUT\fR] [\fIINPUT\fR]

+.br
+.SH "DESCRIPTION"
+\fBage\fR encrypts or decrypts \fIINPUT\fR to \fIOUTPUT\fR\. The \fIINPUT\fR argument is optional and defaults to standard input\. Only a single \fIINPUT\fR file may be specified\. If \fB\-o\fR is not specified, \fIOUTPUT\fR defaults to standard output\.
+.P
+If \fB\-p\fR/\fB\-\-passphrase\fR is specified, the file is encrypted with a passphrase requested interactively\. Otherwise, it's encrypted to one or more \fIRECIPIENTS\fR specified with \fB\-r\fR/\fB\-\-recipient\fR or \fB\-R\fR/\fB\-\-recipients\-file\fR\. Every recipient can decrypt the file\.
+.P
+In \fB\-d\fR/\fB\-\-decrypt\fR mode, passphrase\-encrypted files are detected automatically and the passphrase is requested interactively\. Otherwise, one or more \fIIDENTITIES\fR specified with \fB\-i\fR/\fB\-\-identity\fR are used to decrypt the file\.
+.P
+\fBage\fR encrypted files are binary and not malleable, with around 200 bytes of overhead per recipient, plus 16 bytes every 64KiB of plaintext\.
+.SH "OPTIONS"
+.TP
+\fB\-o\fR, \fB\-\-output\fR=\fIOUTPUT\fR
+Write encrypted or decrypted file to \fIOUTPUT\fR instead of standard output\. If \fIOUTPUT\fR already exists it will be overwritten\.
+.IP
+If encrypting without \fB\-\-armor\fR, \fBage\fR will refuse to output binary to a TTY\. This can be forced by specifying \fB\-\fR as \fIOUTPUT\fR\.
+.TP
+\fB\-\-version\fR
+Print the version and exit\.
+.SS "Encryption options"
+.TP
+\fB\-e\fR, \fB\-\-encrypt\fR
+Encrypt \fIINPUT\fR to \fIOUTPUT\fR\. This is the default\.
+.TP
+\fB\-r\fR, \fB\-\-recipient\fR=\fIRECIPIENT\fR
+Encrypt to the explicitly specified \fIRECIPIENT\fR\. See the \fIRECIPIENTS AND IDENTITIES\fR section for possible recipient formats\.
+.IP
+This option can be repeated and combined with other recipient flags, and the file can be decrypted by all provided recipients independently\.
+.TP
+\fB\-R\fR, \fB\-\-recipients\-file\fR=\fIPATH\fR
+Encrypt to the \fIRECIPIENTS\fR listed in the file at \fIPATH\fR, one per line\. Empty lines and lines starting with \fB#\fR are ignored as comments\.
+.IP
+If \fIPATH\fR is \fB\-\fR, the recipients are read from standard input\. In this case, the \fIINPUT\fR argument must be specified\.
+.IP
+This option can be repeated and combined with other recipient flags, and the file can be decrypted by all provided recipients independently\.
+.TP
+\fB\-p\fR, \fB\-\-passphrase\fR
+Encrypt with a passphrase, requested interactively from the terminal\. \fBage\fR will offer to auto\-generate a secure passphrase\.
+.IP
+This option can't be used with other recipient flags\.
+.TP
+\fB\-a\fR, \fB\-\-armor\fR
+Encrypt to an ASCII\-only "armored" encoding\.
+.IP
+\fBage\fR armor is a strict version of PEM with type \fBAGE ENCRYPTED FILE\fR, canonical "strict" Base64, no headers, and no support for leading and trailing extra data\.
+.IP
+Decryption transparently detects and decodes ASCII armoring\.
+.TP
+\fB\-i\fR, \fB\-\-identity\fR=\fIPATH\fR
+Encrypt to the \fIRECIPIENTS\fR corresponding to the \fIIDENTITIES\fR listed in the file at \fIPATH\fR\. This is equivalent to converting the file at \fIPATH\fR to a recipients file with \fBage\-keygen \-y\fR and then passing that to \fB\-R\fR/\fB\-\-recipients\-file\fR\.
+.IP
+For the format of \fIPATH\fR, see the definition of \fB\-i\fR/\fB\-\-identity\fR in the \fIDecryption options\fR section\.
+.IP
+\fB\-e\fR/\fB\-\-encrypt\fR must be explicitly specified when using \fB\-i\fR/\fB\-\-identity\fR in encryption mode to avoid confusion\.
+.TP
+\fB\-j\fR \fIPLUGIN\fR
+Encrypt using the data\-less \fIplugin\fR \fIPLUGIN\fR\.
+.IP
+This is equivalent to using \fB\-i\fR/\fB\-\-identity\fR with a file that contains a single plugin \fBIDENTITY\fR that encodes no plugin\-specific data\.
+.IP
+\fB\-e\fR/\fB\-\-encrypt\fR must be explicitly specified when using \fB\-j\fR in encryption mode to avoid confusion\.
+.SS "Decryption options"
+.TP
+\fB\-d\fR, \fB\-\-decrypt\fR
+Decrypt \fIINPUT\fR to \fIOUTPUT\fR\.
+.IP
+If \fIINPUT\fR is passphrase encrypted, it will be automatically detected and the passphrase will be requested interactively\. Otherwise, the \fIIDENTITIES\fR specified with \fB\-i\fR/\fB\-\-identity\fR are used\.
+.IP
+ASCII armoring is transparently detected and decoded\.
+.TP
+\fB\-i\fR, \fB\-\-identity\fR=\fIPATH\fR
+Decrypt using the \fIIDENTITIES\fR at \fIPATH\fR\.
+.IP
+\fIPATH\fR may be one of the following:
+.IP
+a\. A file listing \fIIDENTITIES\fR one per line\. Empty lines and lines starting with "\fB#\fR" are ignored as comments\.
+.IP
+b\. A passphrase encrypted age file, containing \fIIDENTITIES\fR one per line like above\. The passphrase is requested interactively\. Note that passphrase\-protected identity files are not necessary for most use cases, where access to the encrypted identity file implies access to the whole system\.
+.IP
+c\. An SSH private key file, in PKCS#1, PKCS#8, or OpenSSH format\. If the private key is password\-protected, the password is requested interactively only if the SSH identity matches the file\. See the \fISSH keys\fR section for more information, including supported key types\.
+.IP
+d\. "\fB\-\fR", causing one of the options above to be read from standard input\. In this case, the \fIINPUT\fR argument must be specified\.
+.IP
+This option can be repeated\. Identities are tried in the order in which are provided, and the first one matching one of the file's recipients is used\. Unused identities are ignored, but it is an error if the \fIINPUT\fR file is passphrase\-encrypted and \fB\-i\fR/\fB\-\-identity\fR is specified\.
+.TP
+\fB\-j\fR \fIPLUGIN\fR
+Decrypt using the data\-less \fIplugin\fR \fIPLUGIN\fR\.
+.IP
+This is equivalent to using \fB\-i\fR/\fB\-\-identity\fR with a file that contains a single plugin \fBIDENTITY\fR that encodes no plugin\-specific data\.
+.SH "RECIPIENTS AND IDENTITIES"
+\fBRECIPIENTS\fR are public values, like a public key, that a file can be encrypted to\. \fBIDENTITIES\fR are private values, like a private key, that allow decrypting a file encrypted to the corresponding \fBRECIPIENT\fR\.
+.SS "Native keys"
+Native \fBage\fR key pairs are generated with age\-keygen(1), and provide small encodings and strong encryption based on X25519 for classic keys, and X25519 + ML\-KEM\-768 for post\-quantum hybrid keys\. The post\-quantum hybrid keys are secure against future quantum computers and are the recommended recipient type for most applications\.
+.P
+A hybrid \fBRECIPIENT\fR encoding begins with \fBage1pq1\fR and looks like the following:
+.IP "" 4
+.nf
+age1pq167[\|\.\|\.\|\. 1950 more characters \|\.\|\.\|\.]
+.fi
+.IP "" 0
+.P
+A hybrid \fBIDENTITY\fR encoding begins with \fBAGE\-SECRET\-KEY\-PQ\-1\fR and looks like the following:
+.IP "" 4
+.nf
+AGE\-SECRET\-KEY\-PQ\-1K30MYPZAHAXHR22YHH27EGDVLU0QNSUH3DSV7J7NR3X6D9LHXNWSDLTV4T
+.fi
+.IP "" 0
+.P
+A classic \fBRECIPIENT\fR encoding begins with \fBage1\fR and looks like the following:
+.IP "" 4
+.nf
+age1gde3ncmahlqd9gg50tanl99r960llztrhfapnmx853s4tjum03uqfssgdh
+.fi
+.IP "" 0
+.P
+A classic \fBIDENTITY\fR encoding begins with \fBAGE\-SECRET\-KEY\-1\fR and looks like the following:
+.IP "" 4
+.nf
+AGE\-SECRET\-KEY\-1KTYK6RVLN5TAPE7VF6FQQSKZ9HWWCDSKUGXXNUQDWZ7XXT5YK5LSF3UTKQ
+.fi
+.IP "" 0
+.P
+A file can't be encrypted to both post\-quantum and classic keys, as that would defeat the post\-quantum security of the encryption\.
+.P
+An encrypted file can't be linked to the native recipient it's encrypted to without access to the corresponding identity\.
+.SS "SSH keys"
+As a convenience feature, \fBage\fR also supports encrypting to RSA or Ed25519 ssh(1) keys\. RSA keys must be at least 2048 bits\. This feature employs more complex cryptography, and should only be used when a native key is not available for the recipient\. Note that SSH keys might not be protected long\-term by the recipient, since they are revokable when used only for authentication\.
+.P
+A \fBRECIPIENT\fR encoding is an SSH public key in \fBauthorized_keys\fR format (see the \fBAUTHORIZED_KEYS FILE FORMAT\fR section of sshd(8)), starting with \fBssh\-rsa\fR or \fBssh\-ed25519\fR, like the following:
+.IP "" 4
+.nf
+ssh\-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDULTit0KUehbi[\|\.\|\.\|\.]GU4BtElAbzh8=
+ssh\-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIH9pO5pz22JZEas[\|\.\|\.\|\.]l1uZc31FGYMXa
+.fi
+.IP "" 0
+.P
+The comment at the end of the line, if present, is ignored\.
+.P
+In recipient files passed to \fB\-R\fR/\fB\-\-recipients\-file\fR, unsupported but valid SSH public keys are ignored with a warning, to facilitate using \fBauthorized_keys\fR or GitHub \fB\.keys\fR files\. (See \fIEXAMPLES\fR\.)
+.P
+An \fBIDENTITY\fR is an SSH private key \fIfile\fR passed individually to \fB\-i\fR/\fB\-\-identity\fR\. Note that keys held on hardware tokens such as YubiKeys or accessed via ssh\-agent(1) are not supported\.
+.P
+An encrypted file \fIcan\fR be linked to the SSH public key it was encrypted to\. This is so that \fBage\fR can identify the correct SSH private key before requesting its password, if any\.
+.SS "Plugins"
+\fBage\fR can be extended through plugins\. A plugin is only loaded if a corresponding \fBRECIPIENT\fR or \fBIDENTITY\fR is specified\. (Simply decrypting a file encrypted with a plugin will not cause it to load, for security reasons among others\.)
+.P
+A \fBRECIPIENT\fR for a plugin named \fBexample\fR starts with \fBage1example1\fR, while an \fBIDENTITY\fR starts with \fBAGE\-PLUGIN\-EXAMPLE\-1\fR\. They both encode arbitrary plugin\-specific data, and are generated by the plugin\.
+.P
+When either is specified, \fBage\fR searches for \fBage\-plugin\-example\fR in the PATH and executes it to perform the file header encryption or decryption\. The plugin may request input from the user through \fBage\fR to complete the operation\.
+.P
+Plugins can be freely mixed with other plugins or natively supported keys\.
+.P
+A plugin is not bound to only encrypt or decrypt files meant for or generated by the plugin\. For example, a plugin can be used to decrypt files encrypted to a native X25519 \fBRECIPIENT\fR or even with a passphrase\. Similarly, a plugin can encrypt a file such that it can be decrypted without the use of any plugin\.
+.P
+Plugins for which the \fBIDENTITY\fR/\fBRECIPIENT\fR distinction doesn't make sense (such as a symmetric encryption plugin) may generate only an \fBIDENTITY\fR and instruct the user to perform encryption with the \fB\-e\fR/\fB\-\-encrypt\fR and \fB\-i\fR/\fB\-\-identity\fR flags\. Plugins for which the concept of separate identities doesn't make sense (such as a password\-encryption plugin) may instruct the user to use the \fB\-j\fR flag\.
+.P
+\fBage\fR can natively encrypt to recipients starting with \fBage1tag1\fR (using P\-256 ECDH) or \fBage1tagpq1\fR (using the ML\-KEM\-768 + P\-256 post\-quantum hybrid)\. These are intended to be the public side of private keys held in hardware\.
+.P
+They are directly supported to avoid the need to install the plugin, which may be platform\-specific, on the encrypting side\.
+.P
+The tag reduces privacy, by allowing an observer to correlate files with a recipient (but not files amongst them without knowledge of the recipient), but this is also a desirable property for hardware keys that require user interaction for each decryption operation\.
+.SH "EXIT STATUS"
+\fBage\fR will exit 0 if and only if encryption or decryption are successful for the full length of the input\.
+.P
+If an error occurs during decryption, partial output might still be generated, but only if it was possible to securely authenticate it\. No unauthenticated output is ever released\.
+.SH "BACKWARDS COMPATIBILITY"
+Files encrypted with a stable version (not alpha, beta, or release candidate) of \fBage\fR, or with any v1\.0\.0 beta or release candidate, will decrypt with any later version of the tool\.
+.P
+If decrypting older files poses a security risk, doing so might cause an error by default\. In this case, a flag will be provided to force the operation\.
+.SH "EXAMPLES"

+
+<h2 id="RECIPIENTS-AND-IDENTITIES">RECIPIENTS AND IDENTITIES</h2>
+
+<p><code>RECIPIENTS</code> are public values, like a public key, that a file can be encrypted
+to. <code>IDENTITIES</code> are private values, like a private key, that allow decrypting
+a file encrypted to the corresponding <code>RECIPIENT</code>.</p>
+
+<h3 id="Native-keys">Native keys</h3>
+
+<p>Native <code>age</code> key pairs are generated with <a class="man-ref" href="age-keygen.1.html">age-keygen<span class="s">(1)</span></a>, and provide small
+encodings and strong encryption based on X25519 for classic keys, and X25519 +
+ML-KEM-768 for post-quantum hybrid keys. The post-quantum hybrid keys are secure
+against future quantum computers and are the recommended recipient type for most
+applications.</p>
+
+<p>A hybrid <code>RECIPIENT</code> encoding begins with <code>age1pq1</code> and looks like the following:</p>
+
+<pre><code>age1pq167[... 1950 more characters ...]
+</code></pre>
+
+<p>A hybrid <code>IDENTITY</code> encoding begins with <code>AGE-SECRET-KEY-PQ-1</code> and looks like
+the following:</p>
+
+<pre><code>AGE-SECRET-KEY-PQ-1K30MYPZAHAXHR22YHH27EGDVLU0QNSUH3DSV7J7NR3X6D9LHXNWSDLTV4T
+</code></pre>
+
+<p>A classic <code>RECIPIENT</code> encoding begins with <code>age1</code> and looks like the following:</p>
+
+<pre><code>age1gde3ncmahlqd9gg50tanl99r960llztrhfapnmx853s4tjum03uqfssgdh
+</code></pre>
+
+<p>A classic <code>IDENTITY</code> encoding begins with <code>AGE-SECRET-KEY-1</code> and looks like the
+following:</p>
+
+<pre><code>AGE-SECRET-KEY-1KTYK6RVLN5TAPE7VF6FQQSKZ9HWWCDSKUGXXNUQDWZ7XXT5YK5LSF3UTKQ
+</code></pre>
+
+<p>A file can't be encrypted to both post-quantum and classic keys, as that would
+defeat the post-quantum security of the encryption.</p>
+
+<p>An encrypted file can't be linked to the native recipient it's encrypted to
+without access to the corresponding identity.</p>
+
+<h3 id="SSH-keys">SSH keys</h3>
+
+<p>As a convenience feature, <code>age</code> also supports encrypting to RSA or Ed25519
+<span class="man-ref">ssh<span class="s">(1)</span></span> keys. RSA keys must be at least 2048 bits. This feature employs more
+complex cryptography, and should only be used when a native key is not available
+for the recipient. Note that SSH keys might not be protected long-term by the
+recipient, since they are revokable when used only for authentication.</p>
+
+<p>A <code>RECIPIENT</code> encoding is an SSH public key in <code>authorized_keys</code> format
+(see the <code>AUTHORIZED_KEYS FILE FORMAT</code> section of <span class="man-ref">sshd<span class="s">(8)</span></span>), starting with
+<code>ssh-rsa</code> or <code>ssh-ed25519</code>, like the following:</p>
+
+<pre><code>ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDULTit0KUehbi[...]GU4BtElAbzh8=
+ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIH9pO5pz22JZEas[...]l1uZc31FGYMXa
+</code></pre>
+
+<p>The comment at the end of the line, if present, is ignored.</p>
+
+<p>In recipient files passed to <code>-R</code>/<code>--recipients-file</code>, unsupported but valid
+SSH public keys are ignored with a warning, to facilitate using
+<code>authorized_keys</code> or GitHub <code>.keys</code> files. (See <a href="#EXAMPLES" title="EXAMPLES" data-bare-link="true">EXAMPLES</a>.)</p>
+
+<p>An <code>IDENTITY</code> is an SSH private key <em>file</em> passed individually to
+<code>-i</code>/<code>--identity</code>. Note that keys held on hardware tokens such as YubiKeys
+or accessed via <span class="man-ref">ssh-agent<span class="s">(1)</span></span> are not supported.</p>
+
+<p>An encrypted file <em>can</em> be linked to the SSH public key it was encrypted to.
+This is so that <code>age</code> can identify the correct SSH private key before
+requesting its password, if any.</p>
+
+<h3 id="Plugins">Plugins</h3>
+
+<p><code>age</code> can be extended through plugins. A plugin is only loaded if a corresponding
+<code>RECIPIENT</code> or <code>IDENTITY</code> is specified. (Simply decrypting a file encrypted with
+a plugin will not cause it to load, for security reasons among others.)</p>
+
+<p>A <code>RECIPIENT</code> for a plugin named <code>example</code> starts with <code>age1example1</code>, while an
+<code>IDENTITY</code> starts with <code>AGE-PLUGIN-EXAMPLE-1</code>. They both encode arbitrary
+plugin-specific data, and are generated by the plugin.</p>
+
+<p>When either is specified, <code>age</code> searches for <code>age-plugin-example</code> in the PATH
+and executes it to perform the file header encryption or decryption. The plugin
+may request input from the user through <code>age</code> to complete the operation.</p>
+
+<p>Plugins can be freely mixed with other plugins or natively supported keys.</p>
+
+<p>A plugin is not bound to only encrypt or decrypt files meant for or generated by
+the plugin. For example, a plugin can be used to decrypt files encrypted to a
+native X25519 <code>RECIPIENT</code> or even with a passphrase. Similarly, a plugin can
+encrypt a file such that it can be decrypted without the use of any plugin.</p>
+
+<p>Plugins for which the <code>IDENTITY</code>/<code>RECIPIENT</code> distinction doesn't make sense
+(such as a symmetric encryption plugin) may generate only an <code>IDENTITY</code> and
+instruct the user to perform encryption with the <code>-e</code>/<code>--encrypt</code> and
+<code>-i</code>/<code>--identity</code> flags. Plugins for which the concept of separate identities
+doesn't make sense (such as a password-encryption plugin) may instruct the user
+to use the <code>-j</code> flag.</p>
+
+<h4 id="Tagged-recipients">Tagged recipients</h4>
+
+<p><code>age</code> can natively encrypt to recipients starting with <code>age1tag1</code> (using P-256
+ECDH) or <code>age1tagpq1</code> (using the ML-KEM-768 + P-256 post-quantum hybrid). These
+are intended to be the public side of private keys held in hardware.</p>
+
+<p>They are directly supported to avoid the need to install the plugin, which may
+be platform-specific, on the encrypting side.</p>
+
+<p>The tag reduces privacy, by allowing an observer to correlate files with a
+recipient (but not files amongst them without knowledge of the recipient),
+but this is also a desirable property for hardware keys that require user
+interaction for each decryption operation.</p>
+
+<h2 id="EXIT-STATUS">EXIT STATUS</h2>
+
+<p><code>age</code> will exit 0 if and only if encryption or decryption are successful for the
+full length of the input.</p>
+
+<p>If an error occurs during decryption, partial output might still be generated,
+but only if it was possible to securely authenticate it. No unauthenticated
+output is ever released.</p>
+
+<h2 id="BACKWARDS-COMPATIBILITY">BACKWARDS COMPATIBILITY</h2>
+
+<p>Files encrypted with a stable version (not alpha, beta, or release candidate) of
+<code>age</code>, or with any v1.0.0 beta or release candidate, will decrypt with any later
+version of the tool.</p>
+
+<p>If decrypting older files poses a security risk, doing so might cause an error
+by default. In this case, a flag will be provided to force the operation.</p>
+

+age(1) -- simple, modern, and secure file encryption
+====================================================
+
+## SYNOPSIS
+
+`age` [`--encrypt`] (`-r` <RECIPIENT> | `-R` <PATH>)... [`--armor`] [`-o` <OUTPUT>] [<INPUT>]<br>
+`age` [`--encrypt`] `--passphrase` [`--armor`] [`-o` <OUTPUT>] [<INPUT>]<br>
+`age` `--decrypt` [`-i` <PATH> | `-j` <PLUGIN>]... [`-o` <OUTPUT>] [<INPUT>]<br>
+
+## DESCRIPTION
+
+`age` encrypts or decrypts <INPUT> to <OUTPUT>. The <INPUT> argument is
+optional and defaults to standard input. Only a single <INPUT> file may be
+specified. If `-o` is not specified, <OUTPUT> defaults to standard output.
+
+If `-p`/`--passphrase` is specified, the file is encrypted with a passphrase
+requested interactively. Otherwise, it's encrypted to one or more
+[RECIPIENTS][RECIPIENTS AND IDENTITIES] specified with `-r`/`--recipient` or
+`-R`/`--recipients-file`. Every recipient can decrypt the file.
+
+In `-d`/`--decrypt` mode, passphrase-encrypted files are detected automatically
+and the passphrase is requested interactively. Otherwise, one or more
+[IDENTITIES][RECIPIENTS AND IDENTITIES] specified with `-i`/`--identity` are
+used to decrypt the file.
+
+`age` encrypted files are binary and not malleable, with around 200 bytes of
+overhead per recipient, plus 16 bytes every 64KiB of plaintext.
+
+## OPTIONS
+
+* `-o`, `--output`=<OUTPUT>:
+    Write encrypted or decrypted file to <OUTPUT> instead of standard output.
+    If <OUTPUT> already exists it will be overwritten.
+
+    If encrypting without `--armor`, `age` will refuse to output binary to a
+    TTY. This can be forced by specifying `-` as <OUTPUT>.
+
+* `--version`:
+    Print the version and exit.
+
+### Encryption options
+
+* `-e`, `--encrypt`:
+    Encrypt <INPUT> to <OUTPUT>. This is the default.
+
+* `-r`, `--recipient`=<RECIPIENT>:
+    Encrypt to the explicitly specified <RECIPIENT>. See the
+    [RECIPIENTS AND IDENTITIES][] section for possible recipient formats.
+
+    This option can be repeated and combined with other recipient flags,
+    and the file can be decrypted by all provided recipients independently.
+
+* `-R`, `--recipients-file`=<PATH>:
+    Encrypt to the [RECIPIENTS][RECIPIENTS AND IDENTITIES] listed in the
+    file at <PATH>, one per line. Empty lines and lines starting with `#`
+    are ignored as comments.
+
+    If <PATH> is `-`, the recipients are read from standard input. In
+    this case, the <INPUT> argument must be specified.
+
+    This option can be repeated and combined with other recipient flags,
+    and the file can be decrypted by all provided recipients independently.
+
+* `-p`, `--passphrase`:
+    Encrypt with a passphrase, requested interactively from the terminal.
+    `age` will offer to auto-generate a secure passphrase.
+
+    This option can't be used with other recipient flags.
+
+* `-a`, `--armor`:
+    Encrypt to an ASCII-only "armored" encoding.
+
+    `age` armor is a strict version of PEM with type `AGE ENCRYPTED FILE`,
+    canonical "strict" Base64, no headers, and no support for leading and
+    trailing extra data.
+
+    Decryption transparently detects and decodes ASCII armoring.
+
+* `-i`, `--identity`=<PATH>:
+    Encrypt to the [RECIPIENTS][RECIPIENTS AND IDENTITIES] corresponding to the
+    [IDENTITIES][RECIPIENTS AND IDENTITIES] listed in the file at <PATH>. This
+    is equivalent to converting the file at <PATH> to a recipients file with
+    `age-keygen -y` and then passing that to `-R`/`--recipients-file`.
+
+    For the format of <PATH>, see the definition of `-i`/`--identity` in the
+    [Decryption options][] section.
+
+    `-e`/`--encrypt` must be explicitly specified when using `-i`/`--identity`
+    in encryption mode to avoid confusion.
+
+* `-j` <PLUGIN>:
+    Encrypt using the data-less [plugin][Plugins] <PLUGIN>.
+
+    This is equivalent to using `-i`/`--identity` with a file that contains a
+    single plugin `IDENTITY` that encodes no plugin-specific data.
+
+    `-e`/`--encrypt` must be explicitly specified when using `-j` in encryption
+    mode to avoid confusion.
+
+### Decryption options
+
+* `-d`, `--decrypt`:
+    Decrypt <INPUT> to <OUTPUT>.
+
+    If <INPUT> is passphrase encrypted, it will be automatically detected
+    and the passphrase will be requested interactively. Otherwise, the
+    [IDENTITIES][RECIPIENTS AND IDENTITIES] specified with `-i`/`--identity`
+    are used.
+
+    ASCII armoring is transparently detected and decoded.
+
+* `-i`, `--identity`=<PATH>:
+    Decrypt using the [IDENTITIES][RECIPIENTS AND IDENTITIES] at <PATH>.
+
+    <PATH> may be one of the following:
+
+    a\. A file listing [IDENTITIES][RECIPIENTS AND IDENTITIES] one per line.
+    Empty lines and lines starting with "`#`" are ignored as comments.
+
+    b\. A passphrase encrypted age file, containing
+    [IDENTITIES][RECIPIENTS AND IDENTITIES] one per line like above.
+    The passphrase is requested interactively. Note that passphrase-protected
+    identity files are not necessary for most use cases, where access to the
+    encrypted identity file implies access to the whole system.
+
+    c\. An SSH private key file, in PKCS#1, PKCS#8, or OpenSSH format.
+    If the private key is password-protected, the password is requested
+    interactively only if the SSH identity matches the file. See the
+    [SSH keys][] section for more information, including supported key types.
+
+    d\. "`-`", causing one of the options above to be read from standard input.
+    In this case, the <INPUT> argument must be specified.
+
+    This option can be repeated. Identities are tried in the order in which are
+    provided, and the first one matching one of the file's recipients is used.
+    Unused identities are ignored, but it is an error if the <INPUT> file is
+    passphrase-encrypted and `-i`/`--identity` is specified.
+
+* `-j` <PLUGIN>:
+    Decrypt using the data-less [plugin][Plugins] <PLUGIN>.
+
+    This is equivalent to using `-i`/`--identity` with a file that contains a
+    single plugin `IDENTITY` that encodes no plugin-specific data.
+
+## RECIPIENTS AND IDENTITIES
+
+`RECIPIENTS` are public values, like a public key, that a file can be encrypted
+to. `IDENTITIES` are private values, like a private key, that allow decrypting
+a file encrypted to the corresponding `RECIPIENT`.
+
+### Native keys
+
+Native `age` key pairs are generated with age-keygen(1), and provide small
+encodings and strong encryption based on X25519 for classic keys, and X25519 +
+ML-KEM-768 for post-quantum hybrid keys. The post-quantum hybrid keys are secure
+against future quantum computers and are the recommended recipient type for most
+applications.
+
+A hybrid `RECIPIENT` encoding begins with `age1pq1` and looks like the following:
+
+    age1pq167[... 1950 more characters ...]
+
+A hybrid `IDENTITY` encoding begins with `AGE-SECRET-KEY-PQ-1` and looks like
+the following:
+
+    AGE-SECRET-KEY-PQ-1K30MYPZAHAXHR22YHH27EGDVLU0QNSUH3DSV7J7NR3X6D9LHXNWSDLTV4T
+
+A classic `RECIPIENT` encoding begins with `age1` and looks like the following:
+
+    age1gde3ncmahlqd9gg50tanl99r960llztrhfapnmx853s4tjum03uqfssgdh
+
+A classic `IDENTITY` encoding begins with `AGE-SECRET-KEY-1` and looks like the
+following:
+
+    AGE-SECRET-KEY-1KTYK6RVLN5TAPE7VF6FQQSKZ9HWWCDSKUGXXNUQDWZ7XXT5YK5LSF3UTKQ
+
+A file can't be encrypted to both post-quantum and classic keys, as that would
+defeat the post-quantum security of the encryption.
+
+An encrypted file can't be linked to the native recipient it's encrypted to
+without access to the corresponding identity.
+
+### SSH keys
+
+As a convenience feature, `age` also supports encrypting to RSA or Ed25519
+ssh(1) keys. RSA keys must be at least 2048 bits. This feature employs more
+complex cryptography, and should only be used when a native key is not available
+for the recipient. Note that SSH keys might not be protected long-term by the
+recipient, since they are revokable when used only for authentication.
+
+A `RECIPIENT` encoding is an SSH public key in `authorized_keys` format
+(see the `AUTHORIZED_KEYS FILE FORMAT` section of sshd(8)), starting with
+`ssh-rsa` or `ssh-ed25519`, like the following:
+
+    ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDULTit0KUehbi[...]GU4BtElAbzh8=
+    ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIH9pO5pz22JZEas[...]l1uZc31FGYMXa
+
+The comment at the end of the line, if present, is ignored.
+
+In recipient files passed to `-R`/`--recipients-file`, unsupported but valid
+SSH public keys are ignored with a warning, to facilitate using
+`authorized_keys` or GitHub `.keys` files. (See [EXAMPLES][].)
+
+An `IDENTITY` is an SSH private key _file_ passed individually to
+`-i`/`--identity`. Note that keys held on hardware tokens such as YubiKeys
+or accessed via ssh-agent(1) are not supported.
+
+An encrypted file _can_ be linked to the SSH public key it was encrypted to.
+This is so that `age` can identify the correct SSH private key before
+requesting its password, if any.
+
+### Plugins
+
+`age` can be extended through plugins. A plugin is only loaded if a corresponding
+`RECIPIENT` or `IDENTITY` is specified. (Simply decrypting a file encrypted with
+a plugin will not cause it to load, for security reasons among others.)
+
+A `RECIPIENT` for a plugin named `example` starts with `age1example1`, while an
+`IDENTITY` starts with `AGE-PLUGIN-EXAMPLE-1`. They both encode arbitrary
+plugin-specific data, and are generated by the plugin.
+
+When either is specified, `age` searches for `age-plugin-example` in the PATH
+and executes it to perform the file header encryption or decryption. The plugin
+may request input from the user through `age` to complete the operation.
+
+Plugins can be freely mixed with other plugins or natively supported keys.
+
+A plugin is not bound to only encrypt or decrypt files meant for or generated by
+the plugin. For example, a plugin can be used to decrypt files encrypted to a
+native X25519 `RECIPIENT` or even with a passphrase. Similarly, a plugin can
+encrypt a file such that it can be decrypted without the use of any plugin.
+
+Plugins for which the `IDENTITY`/`RECIPIENT` distinction doesn't make sense
+(such as a symmetric encryption plugin) may generate only an `IDENTITY` and
+instruct the user to perform encryption with the `-e`/`--encrypt` and
+`-i`/`--identity` flags. Plugins for which the concept of separate identities
+doesn't make sense (such as a password-encryption plugin) may instruct the user
+to use the `-j` flag.
+
+#### Tagged recipients
+
+`age` can natively encrypt to recipients starting with `age1tag1` (using P-256
+ECDH) or `age1tagpq1` (using the ML-KEM-768 + P-256 post-quantum hybrid). These
+are intended to be the public side of private keys held in hardware.
+
+They are directly supported to avoid the need to install the plugin, which may
+be platform-specific, on the encrypting side.
+
+The tag reduces privacy, by allowing an observer to correlate files with a
+recipient (but not files amongst them without knowledge of the recipient),
+but this is also a desirable property for hardware keys that require user
+interaction for each decryption operation.
+
+## EXIT STATUS
+
+`age` will exit 0 if and only if encryption or decryption are successful for the
+full length of the input.
+
+If an error occurs during decryption, partial output might still be generated,
+but only if it was possible to securely authenticate it. No unauthenticated
+output is ever released.
+
+## BACKWARDS COMPATIBILITY
+
+Files encrypted with a stable version (not alpha, beta, or release candidate) of
+`age`, or with any v1.0.0 beta or release candidate, will decrypt with any later
+version of the tool.
+
+If decrypting older files poses a security risk, doing so might cause an error
+by default. In this case, a flag will be provided to force the operation.
+
+## EXAMPLES
+
+Generate a new post-quantum identity, encrypt data, and decrypt:
+
+    $ age-keygen -pq -o key.txt
+    Public key: age1pq167[... 1950 more characters ...]
+
+    $ tar cvz ~/data | age -r age1pq167[...] > data.tar.gz.age
+
+    $ age -d -o data.tar.gz -i key.txt data.tar.gz.age
+
+Encrypt `example.jpg` to multiple recipients and output to `example.jpg.age`:
+
+    $ age -o example.jpg.age -r age1pq167[...] -r age1pq1e3[...] example.jpg
+
+Encrypt to a list of recipients:
+
+    $ cat > recipients.txt
+    # Alice
+    age1pq167[... 1950 more characters ...]
+    # Bob
+    age1pq1e3[... 1950 more characters ...]
+
+    $ age -R recipients.txt example.jpg > example.jpg.age
+
+Encrypt and decrypt a file using a passphrase:
+
+    $ age -p secrets.txt > secrets.txt.age
+    Enter passphrase (leave empty to autogenerate a secure one):
+    Using the autogenerated passphrase "release-response-step-brand-wrap-ankle-pair-unusual-sword-train".
+
+    $ age -d secrets.txt.age > secrets.txt
+    Enter passphrase:
+
+Encrypt and decrypt with a passphrase-protected identity file:
+
+    $ age-keygen | age -p > key.age
+    Public key: age1yhm4gctwfmrpz87tdslm550wrx6m79y9f2hdzt0lndjnehwj0ukqrjpyx5
+    Enter passphrase (leave empty to autogenerate a secure one):
+    Using the autogenerated passphrase "hip-roast-boring-snake-mention-east-wasp-honey-input-actress".
+
+    $ age -r age1yhm4gctwfmrpz87tdslm550wrx6m79y9f2hdzt0lndjnehwj0ukqrjpyx5 secrets.txt > secrets.txt.age
+
+    $ age -d -i key.age secrets.txt.age > secrets.txt
+    Enter passphrase for identity file "key.age":
+
+Encrypt and decrypt with an SSH public key:
+
+    $ age -R ~/.ssh/id_ed25519.pub example.jpg > example.jpg.age
+
+    $ age -d -i ~/.ssh/id_ed25519 example.jpg.age > example.jpg
+
+Encrypt and decrypt with age-plugin-yubikey:
+
+    $ age-plugin-yubikey # run interactive setup, generate identity file and obtain recipient
+
+    $ age -r age1yubikey1qwt50d05nh5vutpdzmlg5wn80xq5negm4uj9ghv0snvdd3yysf5yw3rhl3t secrets.txt > secrets.txt.age
+
+    $ age -d -i age-yubikey-identity-388178f3.txt secrets.txt.age
+
+Encrypt to the SSH keys of a GitHub user:
+
+    $ curl https://github.com/benjojo.keys | age -R - example.jpg > example.jpg.age
