Pull request overview
This PR updates the get_auth_var_signing_certificate.py script to handle non-standard certificate serial numbers and adds functionality to automatically generate JSON mappings from directories of authenticated files. The key improvement is removing the assumption that certificate serial numbers are valid positive 128-bit integers.
Key Changes:
- Removed the 128-bit positive integer conversion for certificate serial numbers in the matching logic
- Added new directory processing mode that generates JSON mappings for bulk certificate processing
- Extended the return value of
process_auth_fileto include SHA1 and SHA256 thumbprints for convenience

Updates the get_auth_var_signing_certificate.py script to not assume that the certificates uses valid positive integers for the serial of the certificate. Also updates the kek_update_map.json to be script created rather than by hand. This should help reduce human error in the future.
