=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The RC2 encryption algorithm for EVP.

=item EVP_rc2_cbc(),

||
|
|
EVP_rc2_cfb(),
|
||
|
|
EVP_rc2_cfb64(),
|
||
|
|
EVP_rc2_ecb(),
|
||
|
|
EVP_rc2_ofb()
|
||
|
|
|
||
|
|
RC2 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a
|
||
|
|
variable key length cipher with an additional parameter called "effective key
|
||
|
|
bits" or "effective key length". By default both are set to 128 bits.
|
||
|
|
|
||
|
|
=item EVP_rc2_40_cbc(),
|
||
|
|
EVP_rc2_64_cbc()
|
||
|
|
|
||
|
|
RC2 algorithm in CBC mode with a default key length and effective key length of
|
||
|
|
40 and 64 bits.
|
||
|
|
|
||
|
|
WARNING: these functions are obsolete. Their usage should be replaced with the
|
||
|
|
EVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl()
|
||
|
|
functions to set the key length and effective key length.

=head1 NOTES
|
||
|
|
|
||
|
|
Developers should be aware of the negative performance implications of
|
||
|
|
calling these functions multiple times and should consider using
|
||
|
|
L<EVP_CIPHER_fetch(3)> instead.
|
||
|
|
See L<crypto(7)/Performance> for further information.
|
||
|
|
|
||
|
|
=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.
