Subject: [PATCH 08/16] crypto: arm64/sm4 - export reusable CE acceleration functions
Date: Mon, 26 Sep 2022 17:36:12 +0800	[thread overview]
Message-ID: <20220926093620.99898-9-tianjia.zhang@linux.alibaba.com> (raw)
In-Reply-To: <20220926093620.99898-1-tianjia.zhang@linux.alibaba.com>

In the accelerated implementation of the SM4 algorithm using the Crypto
Extension instructions, there are some functions that can be reused in
the upcoming accelerated implementation of the GCM/CCM mode, and the
CBC/CFB encryption is reused in the optimized implementation of SVESM4.
