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'

sipHashWith Source #

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'
