12        const EVP_CIPHER *EVP_sm4_cbc(void);
13        const EVP_CIPHER *EVP_sm4_ecb(void);
14        const EVP_CIPHER *EVP_sm4_cfb(void);

DESCRIPTION

19       The SM4 blockcipher (GB/T 32907-2016) for EVP.
20
21       All modes below use a key length of 128 bits and acts on blocks of 128
22       bits.

24       EVP_sm4_cbc(), EVP_sm4_ecb(), EVP_sm4_cfb(), EVP_sm4_ofb(),
25       EVP_sm4_ctr()
26           The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and
27           CTR modes respectively.

RETURN VALUES

30       These functions return a EVP_CIPHER structure that contains the
31       implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for
32       details of the EVP_CIPHER structure.
