<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>

<meta name="description" content="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."/>

BLAKE2b is the 64-bit-word variant of BLAKE2 and the successor of BLAKE-512. BLAKE2b and BLAKE2s are specified in RFC 7693.

VeraCrypt uses BLAKE2b with its maximum output size of 64 bytes (512 bits) internally in <a href="Argon2id.html" style="text-align:left; color:#0080c0; text-decoration:none">Argon2id</a>. For non-system volume header key derivation, BLAKE2b-512 is reached by selecting the Argon2 key derivation algorithm in VeraCrypt; this corresponds to Argon2id internally. In hash-oriented contexts such as random pool mixing and keyfile generation, the same underlying hash may be displayed as BLAKE2b-512.

BLAKE2b-512 is not offered as a separate PBKDF2-HMAC hash algorithm. To use BLAKE2b-512 in VeraCrypt non-system volume header key derivation, select <a href="Argon2id.html" style="text-align:left; color:#0080c0; text-decoration:none">Argon2id</a>; no separate hash algorithm selection is available for Argon2id.
