Subject: [PATCH v5 1/8] crypto: sm3 - export crypto_sm3_final function
Date: Thu, 9 Jul 2020 16:40:08 +0800 [thread overview]
Message-ID: <20200709084015.21886-2-tianjia.zhang@linux.alibaba.com> (raw)
In-Reply-To: <20200709084015.21886-1-tianjia.zhang@linux.alibaba.com>
Both crypto_sm3_update and crypto_sm3_finup have been
exported, exporting crypto_sm3_final, to avoid having to
use crypto_sm3_finup(desc, NULL, 0, dgst) to calculate
the hash in some cases.
