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);
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_ctr()
The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and CTR modes respectively.
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.
