- newtype HMAC a = HMAC {
- hmacGetDigest :: Digest a
- hmac :: HashAlgorithm a => ByteString -> ByteString -> HMAC a
- hmacAlg :: HashAlgorithm a => a -> ByteString -> ByteString -> HMAC a
- data HMACContext hashalg
- hmacInit :: HashAlgorithm a => ByteString -> HMACContext a

MAC algorithms
newtype HMAC a
Represent an HMAC that is a phantom type with the hash used to produce the mac.
The Eq instance is constant time.
Constructors
| HMAC | |
Fields
| |
Arguments
| :: HashAlgorithm a | |
| => ByteString | Secret key |
| -> ByteString | Message to MAC |
| -> HMAC a |
compute a MAC using the supplied hashing function
Arguments
| :: HashAlgorithm a | |
| => a | the hash algorithm the actual value is unused. |
| -> ByteString | Secret key |
| -> ByteString | Message to MAC |
| -> HMAC a |
compute a HMAC using a specified algorithm
Incremental MAC algorithms
data HMACContext hashalg
Represent an ongoing HMAC state, that can be appended with hmacUpdate
and finalize to an HMAC with hmacFinalize
Arguments
| :: HashAlgorithm a | |
| => ByteString | Secret key |
| -> HMACContext a |
Initialize a new incremental HMAC context
Arguments
| :: HashAlgorithm a | |
| => a | the hash algorithm the actual value is unused. |
| -> ByteString | Secret key |
| -> HMACContext a |
Initialize a new incremental HMAC context with a given hash algorithm.
Arguments
| :: HashAlgorithm a | |
| => HMACContext a | |
| -> ByteString | Message to Mac |
| -> HMACContext a |
Incrementally update a HMAC context
hmacFinalize :: HashAlgorithm a => HMACContext a -> HMAC a
Finalize a HMAC context and return the HMAC.
