MAC algorithms
compute a MAC using the supplied hashing function
value
hmacAlg :: HashAlgorithm a=> athe hash algorithm the actual value is unused.
-> ByteStringSecret key
-> ByteStringMessage to MAC
-> HMAC a
compute a HMAC using a specified algorithm
Incremental MAC algorithms
Represent an ongoing HMAC state, that can be appended with hmacUpdate and finalize to an HMAC with hmacFinalize
Initialize a new incremental HMAC context
value
hmacInitAlg :: HashAlgorithm a=> athe hash algorithm the actual value is unused.
-> ByteStringSecret key
-> HMACContext a
Initialize a new incremental HMAC context with a given hash algorithm.
Incrementally update a HMAC context
Finalize a HMAC context and return the HMAC.
