[Bug 1870955] [NEW] MokManager - Only DER encoded certificate (*.cer/der/crt) is supported

[Adrian Feliks]

Public bug reported:

Installation of VirtualBox requires signing kernel modules.
During installation a certificate is generated. It should be automatically added during system reboot. However, this is not happening.

Manual attempt to add a certificate:
After selecting the generated certificate the following error occurs:
"Only DER encoded certificate (*.cer/der/crt) is supported".
I managed to establish that it was MokManager's fault. It does not allow adding ANY certificate.

Laptop: Acer Aspire 7 A715-74G-78PH
UEFI:   Vendor: Insyde Corp.
	Version: V1.23
	Release Date: 10/25/2019
