Adobe Acrobat DC on windows support this feature. While snap package adobe acrobat is partially functional on linux, as it logs incompatibility message.

So actually I am looking for signing my offer letter pdf for joining I want to do it on ubuntu 20.04. Is there any software (long term supported) for that?***


  1. I will be putting my name in the signature in text or image form.
  2. The whole thing will get digitally signed by some encryption algorithm.

Mostly what I am getting is merely signing and securing the document but not a visible signature. Any wayout?
