Subject: [PATCH v5 11/12] cryptodev: clarify rsa verify with none padding
Date: Wed, 1 Jun 2022 10:02:48 +0100 [thread overview]
Message-ID: <20220601090249.86865-12-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <20220601090249.86865-1-arkadiuszx.kusztal@intel.com>
- Clarified where should output be stored of signature
decryption with padding none.
PMD is not able to know what padding algorithm was used,
therefore decrypted signature should be returned to the user.
- Removed incorrect big-endian constraints.
Not all data in RSA can be treated as big endian integer,
therefore some of the constraints were lifted.
Signed-off-by: Arek Kusztal <arkadiuszx.kusztal@intel.com>
