| 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.
