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.
