The SipHash pseudo-random function

SipHash is a family of pseudo-random functions (a.k.a. keyed hash functions) optimized for speed on short messages.
SipHash computes a 64-bit or 128 bit message authentication code from a variable-length message and 128-bit secret key. This implementation uses the recommended parameters c=2 and d=4.
