Playground → Hash algorithms Live Input data: Supported algorithms. uint64([0] * 8) # Loop through the key and update the state using the _update_state function for i in range(len(key)): # Use . It was designed to be efficient even for short inputs, with performance comparable to non-cryptographic hash functions, such as CityHash; [4]: 496 [2] this can be used to prevent denial-of-service attacks against hash tables ("hash flooding"), [5] or to authenticate network packets.
