EVP_SHA1(3)			    OpenSSL			   EVP_SHA1(3)

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.
