NAME
EVP_sha1 - SHA-1 For EVP
SYNOPSIS
#include <openssl/evp.h>
const EVP_MD *EVP_sha1(void);
DESCRIPTION
SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function standardized
in
NIST FIPS 180-4. The algorithm was designed by the United States National
Security Agency and initially published in 1995.
- EVP_sha1()
-
The SHA-1 algorithm which produces a 160-bit output from a given input.
RETURN VALUES
These functions return a
EVP_MD structure that contains the
implementation of the symmetric cipher. See
EVP_MD_meth_new(3) for
details of the
EVP_MD structure.
CONFORMING TO
NIST FIPS 180-4.
