This is a variable key length cipher with a default key +length of 128 bits. + +=item EVP_rc4_40() + +RC4 stream cipher with 40 bit key length. + +WARNING: this function is obsolete. Its usage should be replaced with the +EVP_rc4() and the EVP_CIPHER_CTX_set_key_length() functions. + +=item EVP_rc4_hmac_md5() + +Authenticated encryption with the RC4 stream cipher with MD5 as HMAC. + +WARNING: this is not intended for usage outside of TLS and requires calling of +some undocumented ctrl functions. These ciphers do not conform to the EVP AEAD +interface. + +=back + +=head1 RETURN VALUES + +These functions return an B<EVP_CIPHER> structure that contains the +implementation of the symmetric cipher.
