PDF Signing, tell me the ways

So normally if you want to sign a PDF you have to get yourself an expensive copy of Adobe. But I was amazed at how many alternatives there are.

This quick little Java app works well

Usage like so
  java -jar SignPDF.jar
--certfile=my_cert.p12 --password=secret
--output=signed.pdf origineel.pdf

Another cool one is this c# project that uses itextsharp located here

Another is this great open source sourceforge project,
in a jiffy this portable signer is probably the fastest!
