| |
Some asymmetric algorithms will get different ciphertext after each encryption, such as SM2, and let testmgr support the testing of such algorithms.
In struct akcipher_testvec, set c and c_size to be empty, skip the comparison of the ciphertext, and compare the decrypted plaintext with m to achieve the test purpose.
