NAME

6       EVP_sha1 - SHA-1 For EVP

DESCRIPTION

14       SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function
15       standardized in NIST FIPS 180-4. The algorithm was designed by the
16       United States National Security Agency and initially published in 1995.
17
18       EVP_sha1()
19           The SHA-1 algorithm which produces a 160-bit output from a given
20           input.
21

RETURN VALUES

23       These functions return a EVP_MD structure that contains the
24       implementation of the symmetric cipher. See EVP_MD_meth_new(3) for
25       details of the EVP_MD structure.
26

CONFORMING TO

28       NIST FIPS 180-4.
