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.
