| 25 | ||
| 26 | The SM4 blockcipher (GB/T 32907-2016) for EVP. | |
| 27 | ||
| 28 | All modes below use a key length of 128 bits and acts on blocks of 128 bits. | |

| 45 | ||
| 46 | These functions return a B<EVP_CIPHER> structure that contains the | |
| 47 | implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for | |
| 48 | details of the B<EVP_CIPHER> structure. | |
