Subject: Re: [PATCH] SecurityPkg/SecureBoot: Support RSA 512 and RSA 384
Date: Fri, 30 Jun 2023 11:56:31 +0000 [thread overview]
Message-ID: <MW4PR11MB5872C7084E7912A758A425098C2AA@MW4PR11MB5872.namprd11.prod.outlook.com> (raw)
In-Reply-To: <PH0PR11MB487003C39250D39F4FDA556CE12AA@PH0PR11MB4870.namprd11.prod.outlook.com>
For 4, I think we can enroll all supported algorithms, or the active algorithm. I don’t think the PCD is needed.
For 5, I suggest to change the data structure to include the algorithm ID.
Thank you
