Subject: [RFC PATCH HBK: 2/8] hw-bound-key: flag-is_hbk added to the tfm
Date: Mon, 5 Sep 2022 20:06:25 +0530 [thread overview]
Message-ID: <20220905143631.2832-3-pankaj.gupta@nxp.com> (raw)
In-Reply-To: <20220905143631.2832-1-pankaj.gupta@nxp.com>
Consumer of the kernel crypto api, after allocating
the transformation, sets this flag based on the basis
of the type of key consumer has. This helps:
- This helps to influence the core processing logic
for the encapsulated algorithm.
- This flag is set by the consumer after allocating
the tfm and before calling the function crypto_xxx_setkey().
