yescrypt is a cryptographic key derivation function function used for password hashing on Fedora Linux, [1] Debian, [2] Ubuntu, [3] and Arch Linux. [4] The function is more resistant to offline password-cracking attacks than SHA-512 . [ 5 ]
The Password Hashing Competition was an open competition announced in 2013 to select one or more password hash functions that can be recognized as a recommended standard. . It was modeled after the successful Advanced Encryption Standard process and NIST hash function competition, but directly organized by cryptographers and security practitione
The GOST hash function, defined in the standards GOST R 34.11-94 and GOST 34.311-95 is a 256-bit cryptographic hash function.It was initially defined in the Russian national standard GOST R 34.11-94 Information Technology – Cryptographic Information Security – Hash Function.
crypt is a POSIX C library function. It is typically used to compute the hash of user account passwords. The function outputs a text string which also encodes the salt (usually the first two characters are the salt itself and the rest is the hashed result), and identifies the hash algorithm used (defaulting to the "traditional" one explained below).
The PBKDF2 key derivation function has five input parameters: [9] DK = PBKDF2(PRF, Password, Salt, c, dkLen) where: PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC)
Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser.This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
The two building blocks of the construction, the algorithms Poly1305 and ChaCha20, were both independently designed, in 2005 and 2008, by Daniel J. Bernstein. [2] [3]In March 2013, a proposal was made to the IETF TLS working group to include Salsa20, a winner of the eSTREAM competition [4] to replace the aging RC4-based ciphersuites.
Key stretching algorithms depend on an algorithm which receives an input key and then expends considerable effort to generate a stretched cipher (called an enhanced key [citation needed]) mimicking randomness and longer key length.
