The SHA (Secure Hash Algorithm) Family currently designates a family of six different hash functions: SHA-0, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 [9, 10] published by the American National Institute of Standards and Technology (NIST). They take variable length input messages and hash them to fixed-length outputs.
Hash functions are functions which take a variable input message and compute a fixed-length message digest for each such message. This digest serves as a digital fingerprint allowing a receiver to check that the original message has not been altered during transmission. Hash functions are unkeyed cryptographic primitives which do not guarantee authenticity. They can be combined with a secret key to produce a message authentication code. They also serve as a cryptographic primitive used in digital signature s ...
