Subject: [PATCH] X.509: Support parsing certificate using SM2 algorithm
Date: Mon, 12 Jul 2021 16:13:52 +0800	[thread overview]
Message-ID: <20210712081352.23692-1-tianjia.zhang@linux.alibaba.com> (raw)

The SM2-with-SM3 certificate generated by latest openssl no longer
reuses the OID_id_ecPublicKey, but directly uses OID_sm2. This patch
supports this type of x509 certificate parsing.
