Subject: [PATCH 3/6] crypto: sm2 - make dependent on sm3 library
Date: Mon, 20 Dec 2021 16:22:48 +0800 [thread overview]
Message-ID: <20211220082251.1445-4-tianjia.zhang@linux.alibaba.com> (raw)
In-Reply-To: <20211220082251.1445-1-tianjia.zhang@linux.alibaba.com>
SM3 generic library is stand-alone implementation, it is necessary
for the calculation of sm2 z digest to depends on SM3 library
instead of sm3-generic.
