Package Hash

Hashing algorithms

Hash functions take arbitrary strings as input, and produce an output of fixed size that is dependent on the input; it should never be possible to derive the input data given only the hash function's output. Hash functions can be used simply as a checksum, or, in association with a public-key algorithm, can be used to implement digital signatures.

The hashing modules here all support the interface described in PEP 247, "API for Cryptographic Hash Functions".
