|
|
EVP_rc4,

|

- 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WARNING: this function is obsolete.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.

=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.
