Subject: [RFC PATCH HBK: 2/8] hw-bound-key: flag-is_hbk added to the tfm
Date: Tue,  6 Sep 2022 12:21:51 +0530	[thread overview]
Message-ID: <20220906065157.10662-3-pankaj.gupta@nxp.com> (raw)
In-Reply-To: <20220906065157.10662-1-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().
