[edk2-devel] [PATCH V7 0/2] Support RSA4096 and RSA3072

["Sheng Wei" <w.sheng@intel.com>]

Patch V7:
Drop raw RSA3072 and RSA4096. Only use gEfiCertX509Guid for RSA3072 and RSA4096
Do the positive tests and the negative tests below. And got all the expected results.

Patch V6:
Remove the changes in MdePkg.
The changes of patch v6 are in CryptoPkg and SecurityPkg.
Set signature type to gEfiCertX509Guid when enroll RSA3072/RSA4096 KEK.
This signature type is used to check the supported signature and show the strings.

Patch V5:
Using define KEY_TYPE_RSASSA to replace the magic number.

Patch V4:
Determine the RSA algorithm by a supported algorithm list.

Patch V3:
Select SHA algorithm automaticly for a unsigned efi image.

Patch V2:
Determine the SHA algorithm by a supported algorithm list.
Create SHA context for each algorithm.

Test Case:
1. Enroll a RSA4096 Cert, and execute an RSA4096 signed efi image under UEFI shell. 
2. Enroll a RSA3072 Cert, and execute an RSA3072 signed efi image under UEFI shell. 
3. Enroll a RSA2048 Cert, and execute an RSA2048 signed efi image under UEFI shell. 
4. Enroll an unsigned efi image, execute the unsigned efi image under UEFI shell

Test Result:
Pass

Negative Test Case:
1) Enroll a RSA2048 Cert, execute an unsigned efi image.
2) Enroll a RSA2048 Cert, execute a RSA4096 signed efi image.
3) Enroll a RSA4096 Cert, execute a RSA3072 signed efi image.
4) Enroll a RSA4096 Cert to both DB and DBX, execute the RSA4096 signed efi image.

Test Result:
Get "Access Denied" when try to execute the efi image.

Sheng Wei (2):
  CryptoPkg/Library/BaseCryptLib: add sha384 and sha512 to
    ImageTimestampVerify
  SecurityPkg/SecureBoot: Support RSA 512 and RSA 384
