Noun
HMAC (plural HMACs)
(cryptography) Initialism of hash-based message authentication code. (a specific type of the message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key)
About halfway down, you’ll see where we perform a quick HMAC calculation to confirm the identity of the sender. Source: Internet
Cryptographic algorithms Cryptographic algorithms defined for use with IPsec include: * HMAC SHA1 SHA2 for integrity protection and authenticity. Source: Internet
Implementation The following pseudocode demonstrates how HMAC may be implemented. Source: Internet
The receiving end is then left with the uncomfortable task of decrypting the message and checking HMAC and padding without revealing the padding length in any way. Source: Internet
HMAC with the full version of MD4 can be forged with this knowledge. Source: Internet
The cryptographic strength of the HMAC depends upon the cryptographic strength of the underlying hash function, the size of its hash output, and on the size and quality of the key. Source: Internet
