Sign PDF with email certificate

Digital Certificates Email Certificate
#1

Hello,

Is possible to digitally sign PDF documents with email certificates?

I can import the certificate to Adobe Acrobat (standard /pro) without any problems, but when i try to digitally sign the error comes.

Thanks!

Jorge.

Hello garsan,

i can do this with PDF X-Change viewer (Pro version is needed or you’ll get an advertisement stamp).
You can also use it on the opensource LibreOffice (aka. OpenOffice) documents (from File menu). If the file is edited, the digital signature is removed, so it can be secure as well.
