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);

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.
