EVP_sha1(3)                         OpenSSL                        EVP_sha1(3)




NAME

       EVP_sha1 - SHA-1 For EVP


LIBRARY

       libcrypto, -lcrypto


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.
