From the developer:
MyPDFSigner is a simple tool to digitally sign PDF documents using tokens stored in a PKCS#11 security device (a smart card, like a citizen card issued by many governments in Europe, or a USB token), or a PKCS#12 file (a *.pfx or *.p12 file). In particular, MyPDFSigner provides PHP, Ruby and Python extensions to sign PDF documents.
