NAME
EVP_rc2_cbc, EVP_rc2_cfb, EVP_rc2_cfb64, EVP_rc2_ecb, EVP_rc2_ofb, EVP_rc2_40_cbc, EVP_rc2_64_cbc - EVP RC2 cipher
SYNOPSIS
#include <openssl/evp.h>
const EVP_CIPHER *EVP_rc2_cbc(void)
const EVP_CIPHER *EVP_rc2_cfb(void)
const EVP_CIPHER *EVP_rc2_cfb64(void)
const EVP_CIPHER *EVP_rc2_ecb(void)
const EVP_CIPHER *EVP_rc2_ofb(void)
const EVP_CIPHER *EVP_rc2_40_cbc(void)
const EVP_CIPHER *EVP_rc2_64_cbc(void)
DESCRIPTION
The
RC2 encryption algorithm for
EVP.
- 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.
- 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.
RETURN VALUES
These functions return an
EVP_CIPHER structure that contains the
implementation of the symmetric cipher. See
EVP_CIPHER_meth_new(3) for
details of the
EVP_CIPHER structure.
