Expand description

An implementation of SipHash 2-4.

See: https://131002.net/siphash/

SipHash is a general-purpose hashing function: it runs at a good speed (competitive with Spooky and City) and permits strong keyed hashing. This lets you key your hash tables from a strong RNG, such as rand::os::OsRng.

Although the SipHash algorithm is considered to be generally strong, it is not intended for cryptographic purposes. As such, all cryptographic uses of this implementation are strongly discouraged.
