Hash message
Did you know?
WebNormally a message authentication code (MAC, for instance HMAC) is used for symmetric integrity and authenticity of the message. In that case a hash can be used with a secret key to protect the message; this is also called a keyed hash. Nowadays authenticated modes of encryption is also used a lot; for example an AEAD cipher such as GCM.

Merkle–Damgård construction A hash function must be able to process an arbitrary-length message into a fixed-length output. This can be achieved by breaking the input up into a series of equally sized blocks, and operating on them in sequence using a one-way compression function. The compression function … See more A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of $${\displaystyle n}$$ bits) that has special properties desirable for a cryptographic application: See more Most cryptographic hash functions are designed to take a string of any length as input and produce a fixed-length hash value.
