"""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".
Submodules:
Crypto.Hash.HMAC
RFC 2104. Keyed-Hashing for Message Authentication.
Crypto.Hash.MD2
RFC1319. Rivest's Message Digest algorithm, with a 128 bit digest. This algorithm is both slow and insecure.
Crypto.Hash.MD4
RFC1320. Rivest's Message Digest algorithm, with a 128 bit digest. This algorithm is insecure.
Crypto.Hash.MD5
RFC1321. Rivest's Message Digest algorithm, with a 128 bit digest. This algorithm is insecure.
Crypto.Hash.RIPEMD
RACE Integrity Primitives Evaluation Message Digest algorithm, with a 160 bit digest.
Crypto.Hash.SHA
Secure Hash Algorithm 1 (SHA-1), with a 160 bit digest. Published in FIPS PUB 180-1/2/3.
Crypto.Hash.SHA224
Secure Hash Algorithm 2 (SHA-2 family), with a 224 bit digest. Published in FIPS PUB 180-2/3.
Crypto.Hash.SHA256
Secure Hash Algorithm 2 (SHA-2 family), with a 256 bit digest. Published in FIPS PUB 180-2/3.
Crypto.Hash.SHA384
Secure Hash Algorithm 2 (SHA-2 family), with a 384 bit digest. Published in FIPS PUB 180-2/3.
Crypto.Hash.SHA512
Secure Hash Algorithm 2 (SHA-2 family), with a 512 bit digest. Published in FIPS PUB 180-2/3.
