Hello everyone,

I have a big problem. I have several pdf documents signed with a self-signed certificate (created by me from Microsoft Internet Information Server).

I have installed my self-signed certificate in Windows 10 operating system and I can open those documents without problems. But when I try to open those documents in Android, IOS (iphone) or Mac OS, I always get the same error: "The file is possible to be damaged or format which Preview View does not be able to recognize" or something like that. I have installed the self-signed certificate in them as well.

I have tested with diferents certificates and pdf versions (when I convert it from a .docx file for example) and I always get the same result in Android, IOS and Mac OS.

What is the problem? What am I doing wrong?

Best regards,

Jarol
