WebHash functions are designed to be fast. You don't want this for passwords. Use scrypt, bcrypt, or PBKDF-2. MD5 was found to be weak back in 1996, and should not be used anymore for cryptographic purposes. SHA-1 is a commonly used replacement, but has similar problems. The SHA-2 family of hash functions are the current replacement of SHA-1.

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. WebHash Function – One way Needed properties for cryptographically secure hash: 1. Computationally infeasible to find the message that has given the hash 2. Should be highly improbable for two messages to hash to the same number (and to find two messages with the same hash).

WebBut it's broken, and thus no longer usable as a cryptographic hash. On the other hand when you have a non cryptographic hash function, you can't really call it "broken", since it never tried to be secure in the first place.
