This is a 39variable key length cipher with an additional parameter called "effective key 40bits" or "effective key length". By default both are set to 128 bits. 41 42=item EVP_rc2_40_cbc(), 43EVP_rc2_64_cbc() 44 45RC2 algorithm in CBC mode with a default key length and effective key length of 4640 and 64 bits. 47 48WARNING: these functions are obsolete. Their usage should be replaced with the 49EVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl() 50functions to set the key length and effective key length. 51 52=back 53 54=head1 RETURN VALUES 55 56These functions return an B<EVP_CIPHER> structure that contains the 57implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for 58details of the B<EVP_CIPHER> structure. 59 60=head1 SEE ALSO 61 62L<evp(7)>, 63L<EVP_EncryptInit(3)>, 64L<EVP_CIPHER_meth_new(3)> 65 66=head1 COPYRIGHT 67 68Copyright 2017-2018 The OpenSSL Project Authors.
