hmacKeyFromString64 :: OctetStream a => a -> HMACKey

Mainly for testing. 64 byte blocksize version.

Note: blocksize is 64 bytes (512 bits) for both SHA1 and SHA256 and even MD5, but 128 bytes (1024 bits) for SHA512

Also it seems that according the spec long keys should be hashed. Even though the hash is half as long (but we use zero padding anyway)

hmacKeyFromString128 :: OctetStream a => a -> HMACKey
