    RSA2048 Secure Boot certificates issued by/for Microsoft,
 
  - as UEFI variable vendor GUID in association with (unspecified)
    Microsoft-owned variables.

//
// - Microsoft.UefiSecureBootLogo.Tests.OutOfBoxVerifyMicrosoftKEKpresent
// - Microsoft.UefiSecureBootLogo.Tests.OutOfBoxConfirmMicrosoftSignatureInDB

// expect the EFI_SIGNATURE_DATA.SignatureOwner GUID to be
// 77FA9ABD-0359-4D32-BD60-28F4E78F784B, when the
// EFI_SIGNATURE_DATA.SignatureData field carries any of the following X509

//
// - "Microsoft Corporation KEK CA 2011" (in KEK)
// - "Microsoft Windows Production PCA 2011" (in db)
// - "Microsoft Corporation UEFI CA 2011" (in db)

// This is despite the fact that the UEFI specification requires
// EFI_SIGNATURE_DATA.SignatureOwner to reflect the agent (i.e., OS,

// EFI_SIGNATURE_DATA.SignatureData, and not the organization that issued
// EFI_SIGNATURE_DATA.SignatureData.
