HMAC-SHA1 generation. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.
FIPS PUB 198-1 The Keyed-Hash Message Authentication Code (HMAC) [14] NIST SP800-185 SHA-3 Derived Functions: cSHAKE, KMAC, TupleHash, and ParallelHash [15] ISO/IEC 9797-1 Mechanisms using a block cipher [16] ISO/IEC 9797-2 Mechanisms using a dedicated hash-function [17] ISO/IEC 9797-3 Mechanisms using a universal hash-function [18]
HMAC-based one-time password (HOTP) is a one-time password (OTP) algorithm based on HMAC. It is a cornerstone of the Initiative for Open Authentication (OATH). HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation. Since then, the algorithm has been adopted by many ...
PBKDF2 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)

HKDF is a simple key derivation function (KDF) based on the HMAC message authentication code. [ 1 ] [ 2 ] It was initially proposed by its authors as a building block in various protocols and applications, as well as to discourage the proliferation of multiple KDF mechanisms. [ 2 ]
