- sipHashWith :: ByteArrayAccess ba => Int -> Int -> SipKey -> ba -> SipHash
- newtype FnvHash32 = FnvHash32 Word32
- newtype FnvHash64 = FnvHash64 Word64
- fnv1Hash :: ByteArrayAccess ba => ba -> FnvHash32

SipHash
Siphash tag value
sipHash :: ByteArrayAccess ba => SipKey -> ba -> SipHash Source
Compute the SipHash tag of a byte array for a given key.
sipHash is equivalent to 'sipHashWith 2 4'
Arguments
| :: ByteArrayAccess ba | |
| => Int | c rounds |
| -> Int | d rounds |
| -> SipKey | key |
| -> ba | data to hash |
| -> SipHash |
Compute the SipHash tag of a byte array for a given key.
The user can choose the C and D numbers of rounds.
calling sipHash is equivalent to 'sipHashWith 2 4'
FNV1 and FNV1a (32 and 64 bits)
FNV1(a) hash (32 bit variants)
FNV1(a) hash (64 bit variants)
fnv1Hash :: ByteArrayAccess ba => ba -> FnvHash32 Source
Compute the FNV1 32 bit hash value of a byte array
fnv1aHash :: ByteArrayAccess ba => ba -> FnvHash32 Source
Compute the FNV1a 32 bit hash value of a byte array
fnv1_64Hash :: ByteArrayAccess ba => ba -> FnvHash64 Source
Compute the FNV1 64 bit hash value of a byte array
fnv1a_64Hash :: ByteArrayAccess ba => ba -> FnvHash64 Source
Compute the FNV1a 64 bit hash value of a byte array
