Append digital signature to PDF documents.

Overview

PDFSign is a stand-alone, fully automatic software application that can append digital signature to PDF documents. To sign PDF documents simply select the PDF file or folder with PDF files, select Digital ID file and push the "Start" button. That's all. The PDF document will signed automatically.

The program's features are:

  • Ease of use
  • Recursive search for PDF documents.
  • No additional plug-ins are required to open documents or verify signatures in Adobe Acrobat or Adobe Reader
  • Apply invisible signatures to a document or a collection of documents
  • Linearize for Fast Web View
  • Certificate information in a PKCS #12 file is used to digitally sign the document.
  • Use Adobe Acrobat or Adobe Reader to verify your signatures.
  • Not requiring full Adobe Acrobat or Adobe Reader plus the Adobe Document Server for Reader Extension !
  • The standard signatures produced by PDFSign are interoperable with the Adobe signature format, and can be verified using the freely available Adobe Reader 6.0+, therefore ensuring embedded signatures have the widest possible reach and can be verified by any recipient.
  • Support for PDF format versions to 1.7.
  • The program is a must have tool for every individual or company that works with PDF documents extensively.

Requirements for PDFSign

  • Mac OS X 10.3.9 or later

It is incredible that this seems to be the only way to add a digital encrypted signature to a PDF document on a Mac, besides Acrobat Professional. It's super straightforward and easy to do. ¡Thanks to the folks at PDFSign!

This program is totally outdated. It is not signed und doesn't use Apple's Keychain. JSignPDF is a better alternative.

There are other ways. Built-in option using Preview is free. http://osxdaily.com/2011/08/17/sign-pdf-with-digital-signature-mac-os-x/

This is not quite true. The tool DigiSigner can create digital encrypted signatures and has much more features (for the same price). And by the way with DigiSigner you can see the document you are going to sign. The option suggested by Etbozo is completely different. It can be useful, but it basically only lets you insert texts and images in your document, not create digital signatures to cryptographically protect your documents.

Dmitry, Thanks for the DigiSigner tip I'll give it a try. A friend told me that none of these "signers" will work because the receiving party has to establish some sort of "handshake" with the document and only Adobe will do. Do you know if this is correct or even legal?

Hi Rampg, not sure what you mean by "handshake". The specification for cryptographic digital signatures in PDF documents is an open standard and part of the PDF specification. So there are tools out there, which implement it and produce exactly the same signatures as Adobe tools. DigiSigner is one of them. There are also many tools, that claim to produce "digital" signatures, where in reality they produce only so called electronic signatures. The difference is, real digital signatures cryptographically protect your documents and ensure the signer's authority, where the electonic signatures just add texts/images to your document's content and don't have any security aspect. Is it maybe what you meant by "that none of these signers will work"? Oh, and DigiSigner produces real cryptographic digital signatures :)
