sipHash :: ByteArrayAccess ba => SipKey -> ba -> SipHash

Compute the SipHash tag of a byte array for a given key.

sipHash is equivalent to 'sipHashWith 2 4'

sipHashWith

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'
