Subject: [PATCH 4/7] crypto: testmgr - support test with different ciphertext per encryption
Date: Sun, 16 Feb 2020 16:59:25 +0800 [thread overview]
Message-ID: <20200216085928.108838-5-tianjia.zhang@linux.alibaba.com> (raw)
In-Reply-To: <20200216085928.108838-1-tianjia.zhang@linux.alibaba.com>
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.
