| 12 | =head1 SYNOPSIS | |

| 18 | const EVP_CIPHER *EVP_ciphername(void) | |
| 19 | ||
| 20 | I<EVP_ciphername> is used a placeholder for any of the described cipher | |
| 21 | functions, such as I<EVP_sm4_cbc>. | |
| 22 | ||
| 23 | =head1 DESCRIPTION | |
| 24 | ||
| 25 | The SM4 blockcipher (GB/T 32907-2016) for EVP. | |
| 26 | ||
| 27 | All modes below use a key length of 128 bits and acts on blocks of 128 bits. | |

| 36 | ||
| 37 | The SM4 blockcipher with a 128-bit key in CBC, ECB, CFB, OFB and CTR modes | |
| 38 | respectively. | |

| 42 | =head1 RETURN VALUES | |
| 43 | ||
| 44 | These functions return a B<EVP_CIPHER> structure that contains the | |
| 45 | implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for | |
| 46 | details of the B<EVP_CIPHER> structure. | |
