[HELP] Sign pdf with x509 #130

Closed hrodrigues1984 closed 3 years ago

hrodrigues1984 commented 3 years ago

Hello,

Thanks in advance for your work, the library is very very nice.

I tried to use an x509 certificate to sign a pdf without the private key. Can you help with this challenge? After a lot of digging and using the library as a starting point, I was able to overcome some issues by changing the default p12 approach to be compatible with x509. Also related to node-forge, for instance, since I don't have access to the private key the pkcs7 object needs to use 'encrypt' instead of 'sign', during the signature creation.

I was also able to sign the pdf, however, none of my oids are working on the document's signature, resulting in a failure. Expected result: Screenshot 2021-03-24 at 19 31 10

Outcome: Screenshot 2021-03-24 at 19 31 27

Can someone help, please?

It is not possible to sign a document without a private key. What you're asking for is not possible.
