| 34 | RC5 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a | |
| 35 | variable key length cipher with an additional "number of rounds" parameter. By | |
| 36 | default the key length is set to 128 bits and 12 rounds. | |

| 40 | =head1 RETURN VALUES | |
| 41 | ||
| 42 | These functions return an B<EVP_CIPHER> structure that contains the | |
| 43 | implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for | |
| 44 | details of the B<EVP_CIPHER> structure. | |
| 45 | ||
| 46 | =head1 BUGS | |
| 47 | ||
| 48 | Currently the number of rounds in RC5 can only be set to 8, 12 or 16. | |
| 49 | This is a limitation of the current RC5 code rather than the EVP interface. | |
