DESCRIPTION

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

25       EVP_sm4_cbc(), EVP_sm4_ecb(), EVP_sm4_cfb(), EVP_sm4_cfb128(),
26       EVP_sm4_ofb(), EVP_sm4_ctr()
27           The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and
28           CTR modes respectively.

RETURN VALUES

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