NAME
EVP_sm4_cbc, EVP_sm4_ecb, EVP_sm4_cfb, EVP_sm4_cfb128, EVP_sm4_ofb, EVP_sm4_ctr - EVP SM4 cipher
SYNOPSIS
#include <openssl/evp.h>
const EVP_CIPHER *EVP_sm4_cbc(void);
const EVP_CIPHER *EVP_sm4_ecb(void);
const EVP_CIPHER *EVP_sm4_cfb(void);
const EVP_CIPHER *EVP_sm4_cfb128(void);
const EVP_CIPHER *EVP_sm4_ofb(void);
const EVP_CIPHER *EVP_sm4_ctr(void);
DESCRIPTION
The
SM4 blockcipher (
GB/T 32907-2016) for
EVP.
All modes below use a key length of 128 bits and acts on blocks of 128 bits.
- EVP_sm4_cbc(), EVP_sm4_ecb(), EVP_sm4_cfb(), EVP_sm4_cfb128(), EVP_sm4_ofb(), EVP_sm4_ctr()
-
The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and CTR modes
respectively.
RETURN VALUES
These functions return a
EVP_CIPHER structure that contains the
implementation of the symmetric cipher. See
EVP_CIPHER_meth_new(3) for
details of the
EVP_CIPHER structure.
