| |
| EVP_md5, |
| EVP_md5_sha1 |
| - MD5 For EVP |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/evp.h> |
| |
| const EVP_MD *EVP_md5(void); |
| const EVP_MD *EVP_md5_sha1(void); |
| |
| =head1 DESCRIPTION |
| |
| MD5 is a cryptographic hash function standardized in RFC 1321 and designed by |
| Ronald Rivest. |
| |
| The CMU Software Engineering Institute considers MD5 unsuitable for further |
| use since its security has been severely compromised. |
| |
| =over 4 |
| |
| =item EVP_md5() |
| |
| The MD5 algorithm which produces a 128-bit output from a given input. |
| |
| =item EVP_md5_sha1() |
| |
| A hash algorithm of SSL v3 that combines MD5 with SHA-1 as described in RFC |
| 6101. |
| |
| WARNING: this algorithm is not intended for non-SSL usage. |
