Detailed Description

This file contains SHA-1 definitions and functions.

The Secure Hash Algorithm 1 (SHA-1) cryptographic hash function is defined in FIPS 180-4: Secure Hash Standard (SHS).

Warning
SHA-1 is considered a weak message digest and its use constitutes a security risk. We recommend considering stronger message digests instead.
