WebbSipHash 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.
