Contents
Description
Implements HMAC (hashed message authentication code) as defined in FIPS 198 http://csrc.nist.gov/publications/fips/fips198/fips-198a.pdf.
- hmac :: HashMethod -> [Octet] -> [Octet] -> [Octet]
- hmac_sha1 :: [Octet] -> [Octet] -> [Octet]
- hmac_md5 :: [Octet] -> [Octet] -> [Octet]
- data HashMethod = HashMethod {
- digest :: [Octet] -> [Octet]
- input_blocksize :: Int
Function Types
Arguments
| :: HashMethod | Hash function and associated block size |
| -> [Octet] | Secret key |
| -> [Octet] | Message text |
| -> [Octet] | Resulting HMAC value |
Generalized function for creating HMACs on a specified hash function.
Compute an HMAC using SHA-1 as the underlying hash function.
Compute an HMAC using MD5 as the underlying hash function.
Data Types
data HashMethod Source
HMAC works over any hash function, which is represented by HashMethod. A hash function and input block size must be specified.
