Acquire a valid digital signature

[bumpyard]

Hi

I want to apply a digital signature to the PDF, I saw the example and did exactly like it with a pfx file, but when I opened the final PDF in Acrobat Reader I saw some warnings that the signature is not valid since it's not trusted (and also other reasons), attached some screen shots.

How do I acquire a trusted signature? do you have recommendations from where I can purchase such a signature?

Thanks,
Roni.

P.S.

I saw in Digicert website (digicert.com) that they sell document signing certificates, but they have a limitation of 5000 documents per year and it's pretty expensive, can I purchase a standard SSL and then export it as pfx? will acrobat accept it and will not display a warning on the signature?

Thanks,
Roni.

Hello,

Thanks for your inquiry. I think you need to Add the Root Certificate on Adobe Trusted Identities, then you can make your signature trusted . Please refer to the attached documentation to accomplish it. If you encounter any problem, please share us with your pfx file.
