14 | =head1 DESCRIPTION | |
15 | ||
16 | SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function standardized | |
17 | in NIST FIPS 180-4. The algorithm was designed by the United States National | |
18 | Security Agency and initially published in 1995. | |
19 | ||
20 | =over 4 | |
21 | ||
22 | =item EVP_sha1() | |
23 | ||
24 | The SHA-1 algorithm which produces a 160-bit output from a given input. | |

29 | =head1 RETURN VALUES | |
30 | ||
31 | These functions return a B<EVP_MD> structure that contains the | |
ae2efd63 | 32 | implementation of the message digest. See L<EVP_MD_meth_new(3)> for |
bbda8ce9 RT |
33 | details of the B<EVP_MD> structure. |
