The Portable Freeware Collection Forums

I did not find any similar software in the database for digitally signing pdf files, so I submit this quite old software as a portable app. It is a very lightweight alternative for using LibreOffice for signing pdf files.

iSafePDF is a free open source PDF protection software.
it allows you to encrypt PDF document, signe them using a certificate and timestamp the signature.
all those features are PDF standards so your document will be readable/editable with all standard PDF programs.

It's a basic program, which does not seem to save any settings at all, so I believe it is a totally portable solution.

The software can be downloaded at http://isafepdf.eurekaa.org/download-isafepdf/

I'll dig into this myself when I have some more time but some questions that jumped out on me were whether you need an existing cert? If so, is there a place to get one? Can you generate one like GPG?

Also, I think PDF Shaper can now sign PDFs
