Hi,

How do I verify a file that contains a digital signature like Adobe (by Trusting certificates)?

That is, how to convert Yellow question mark to Green Check Mark?

PDF24 itself is not able to verify digital signatures of PDF files. This feature is still on our TODO and will be added by one of the upcoming versions.
