| 5 | EVP_md5, |
| 6 | EVP_md5_sha1 |
| 7 | - MD5 For EVP |
| 8 | |
| 9 | =head1 SYNOPSIS |
| 10 | |
| 11 | #include <openssl/evp.h> |
| 12 | |
| 13 | const EVP_MD *EVP_md5(void); |
| 14 | const EVP_MD *EVP_md5_sha1(void); |
| 15 | |
| 16 | =head1 DESCRIPTION |
| 17 | |
| 18 | MD5 is a cryptographic hash function standardized in RFC 1321 and designed by |
| 19 | Ronald Rivest. |
| 20 | |
| 21 | The CMU Software Engineering Institute considers MD5 unsuitable for further |
| 22 | use since its security has been severely compromised. |
| 23 | |

| 25 | |
| 26 | =item EVP_md5() |
| 27 | |
| 28 | The MD5 algorithm which produces a 128-bit output from a given input. |
| 29 | |
| 30 | =item EVP_md5_sha1() |
| 31 | |
| 32 | A hash algorithm of SSL v3 that combines MD5 with SHA-1 as described in RFC |
| 33 | 6101. |
| 34 | |
| 35 | WARNING: this algorithm is not intended for non-SSL usage. |

| 40 | =head1 RETURN VALUES |
| 41 | |
| 42 | These functions return a B<EVP_MD> structure that contains the |
| 43 | implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for |
| 44 | details of the B<EVP_MD> structure. |
