+=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 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.
