=head1 NAME
EVP_rc4,
EVP_rc4_40,
EVP_rc4_hmac_md5
- EVP RC4 stream cipher
=head1 SYNOPSIS
#include <openssl/evp.h>
const EVP_CIPHER *EVP_rc4(void)
const EVP_CIPHER *EVP_rc4_40(void)
const EVP_CIPHER *EVP_rc4_hmac_md5(void)
=head1 DESCRIPTION
The RC4 stream cipher for EVP.
=over 4
=item EVP_rc4()
RC4 stream cipher. 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WARNING: this function is obsolete.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. See L<EVP_CIPHER_meth_new(3)> for
details of the B<EVP_CIPHER> structure.
