Detailed Description

Type declarations and APIs for the SHA-224 algorithm.

SHA-224 is part of the SHA-2 family that is a set of cryptographic hash functions designed by the NSA. It is the successor of the SHA-1 algorithm.

A fixed-sized message digest is computed from variable length input data. The function is practically impossible to revert, and small changes in the input message lead to major changes in the message digest.
