| 5 | EVP_md5 | |
| 6 | - MD5 For EVP | |

| 8 | =head1 SYNOPSIS | |
| 9 | ||
| 10 | #include <openssl/evp.h> | |
| 11 | ||
| 12 | const EVP_MD *EVP_md5(void); | |
| 13 | ||
| 14 | =head1 DESCRIPTION | |
| 15 | ||
| 16 | MD5 is a cryptographic hash function standardized in RFC 1321 and designed by | |
| 17 | Ronald Rivest. | |
| 18 | ||
| 3266cf58 | 19 | The CMU Software Engineering Institute considers MD5 unsuitable for further |
| bbda8ce9 RT |
20 | use since its security has been severely compromised. |
| 21 | ||
| 22 | =over 4 | |
| 23 | ||
| 24 | =item EVP_md5() | |
| 25 | ||
| 26 | The MD5 algorithm which produces a 128-bit output from a given input. | |
| 27 | ||
| 28 | =item EVP_md5_sha1() | |
| 29 | ||
| 30 | A hash algorithm of SSL v3 that combines MD5 with SHA-1 as decirbed in RFC | |
| 31 | 6101. | |
| 32 | ||
| 33 | WARNING: this algorithm is not intended for non-SSL usage. | |

| 38 | =head1 RETURN VALUES | |
| 39 | ||
| 40 | These functions return a B<EVP_MD> structure that contains the | |
| 41 | implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for | |
| 42 | details of the B<EVP_MD> structure. | |
