| |
| RC5 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a |
| variable key length cipher with an additional "number of rounds" parameter. By |
| default the key length is set to 128 bits and 12 rounds. |

| |
| =head1 RETURN VALUES |
| |
| These functions return an B<EVP_CIPHER> structure that contains the |
| implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for |
| details of the B<EVP_CIPHER> structure. |
| |
| =head1 BUGS |
| |
| Currently the number of rounds in RC5 can only be set to 8, 12 or 16. |
| This is a limitation of the current RC5 code rather than the EVP interface. |
