Subject: [PATCH v3 1/3] crypto/secret: move main logic from 'secret' to 'secret_common'.
Date: Mon, 18 May 2020 23:28:02 +0300 [thread overview]
Message-ID: <20200518202804.3761-2-alex-krasikov@yandex-team.ru> (raw)
In-Reply-To: <20200518202804.3761-1-alex-krasikov@yandex-team.ru>
Create base class 'common secret'. Move common data and logic from
'secret' to 'common_secret' class. This allowed adding abstraction layer
for easier adding new 'secret' objects in future.
Convert 'secret' class to child from basic 'secret_common' with 'data'
and 'file' properties.
