Multi-platform transparent client-side encryption of your files in the cloud.
|
|
|
|
Download native binaries of Cryptomator on [cryptomator.org](https://cryptomator.org/) or clone and build Cryptomator using Maven (instructions below).
|
|
|
|
## Features
|
|
|
|
- Works with Dropbox, Google Drive, OneDrive, and any other cloud storage service that synchronizes with a local directory
|
|
- Open Source means: No backdoors, control is better than trust
|
|
- Client-side: No accounts, no data shared with any online service
|
|
- Totally transparent: Just work on the virtual drive as if it were a USB flash drive
|
|
- AES encryption with 256-bit key length
|
|
- Filenames get encrypted, too
|
|
- Use as many vaults in your Dropbox as you want, each having individual passwords
|
|
|
|
### Privacy
|
|
|
|
- 256-bit keys (unlimited strength policy bundled with native binaries)
|
|
- Scrypt key derivation
|
|
- Cryptographically secure random numbers for salts, IVs and the masterkey of course
|
|
- Sensitive data is wiped from the heap asap
|
|
- Lightweight: [Complexity kills security](https://www.schneier.com/essays/archives/1999/11/a_plea_for_simplicit.html)
|
|
|
|
### Consistency
|
|
|
|
- HMAC over file contents to recognize changed ciphertext before decryption
|
|
- I/O operations are transactional and atomic, if the filesystems support it
|
|
- Each file contains all information needed for decryption (except for the key of course), no common metadata means no [SPOF](http://en.wikipedia.org/wiki/Single_point_of_failure)
|
|
|
|
### Security Architecture
|
|
|

|
## Building
|
|
|
|
### Dependencies
|
|
|
|
* Java 8 + JCE unlimited strength policy files (needed for 256-bit keys)
|
|
* Maven 3
|
|
* Optional: OS-dependent build tools for native packaging (see [Windows](https://github.com/cryptomator/cryptomator-win), [OS X](https://github.com/cryptomator/cryptomator-osx), [Debian](https://github.com/cryptomator/cryptomator-deb))
|
|
|
|
### Run Maven
|
|
|
|
```
|
|
cd main
|
|
mvn clean install
|
|
```
