EVP_sha1 - SHA-1 For EVP
#include <openssl/evp.h>
const EVP_MD *EVP_sha1(void);
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.
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.
NIST FIPS 180-4.
