# VeraCrypt - Free Open source disk encryption with strong security for the Paranoid
VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.

Documentation Hash Algorithms Streebog

# Streebog

Streebog is a family of two hash algorithms, Streebog-256 and Streebog-512, defined in the Russian national standard GOST R 34.11-2012 Information Technology - Cryptographic Information Security - Hash Function. It is also described in RFC 6986. It is the competitor of NIST SHA-3 standard.

VeraCrypt uses only Streebog-512 which has an output size of 512 bits.
