Subject: [RFC PATCH HBK: 8/8] dm-crypt: consumer-app setting the flag-is_hbk
Date: Tue, 6 Sep 2022 12:21:57 +0530 [thread overview]
Message-ID: <20220906065157.10662-9-pankaj.gupta@nxp.com> (raw)
In-Reply-To: <20220906065157.10662-1-pankaj.gupta@nxp.com>
Consumer application:
- Adding a flag 'is_hbk', in its "struct crypto_config".
- After fetching the keys, it is setting the above
mentioned flag, based on the key fetched.
-- Note: Supported for trusted keys only.
- After allocating the tfm, and before calling
crypto_xxx_setkey(), setting the tfm flag 'is_hbk':
cc->cipher_tfm.tfms[i]->base.is_hbk = cc->is_hbk;
-- Note: Supported for symmetric-key ciphers only.
