NAME

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)

DESCRIPTION

EVP_rc4()

RC4 stream cipher. This is a variable key length cipher with a default key length of 128 bits.

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WARNING: this function is obsolete.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.

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.
