Cryptographically secured hash function
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. WebThe hash function generates a hash code by operating on two blocks of fixed-length binary data. Hashing algorithm is a process for using the hash function, specifying how the …
