WebHMACSHA512 is a type of keyed hash algorithm that is constructed from the SHA-512 hash function and used as a Hash-based Message Authentication Code (HMAC). The HMAC process mixes a secret key with the message data and hashes the result. The hash value is mixed with the secret key again, and then hashed a second time. WebJun 20, 2024 · Hashcat boasts its ability to crack over 200+ hashing algorithms, but there isn't much documentation on much of them. Hashcat --help shows it has support for HMAC cracking, but it's not very straightforward with the syntax (it just says "1450 HMAC-SHA256 (key = $pass)" ).
