WebSipHash is a cryptographically secure PRF – a keyed hash function – that performs very well for short inputs, hence the name. It was designed by cryptographers Daniel J. Bernstein and Jean-Philippe Aumasson. It is intended as a replacement for some uses of: jhash, md5_transform, sha1_transform , and so forth.

WebBoth ideas are safe if the hash function behaves like a random oracle and has a large enough output (in particular for "idea 1": with a function which outputs n bits at a time, it is expected that the state will enter a cycle of length about 2n/2, after about 2n/2 steps, so if you want "128-bit security", you will need n = 256 or more).
