Detailed Description

Type declarations and APIs for the SHA-1 algorithm.

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

SHA-1 is no longer considered secure against well-funded opponents; replacement by SHA-2 or SHA-3 is recommended.
