=head1 DESCRIPTION
|
|
|
|
The RC5 encryption algorithm for EVP.

|
|
|
|
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.
