Reviewing the source code for the demonstration program will provide a good way to quickly begin using the toolkit. See the link below to "PdfSignerDemo" demonstration program. The processing includes:

1. Input an existing PDF file that has no signatures.
2. Open your private keystore and sign the PDF file.
3. Create and send a time stamp request.
4. Output a PDF file that can then be opened in Acrobat Reader where the signature and signature timestamp are authenticated.

Requires Java libraries from:

• BouncyCastle ( Version 1.5+ need 3 jar files: Provider, Mail and TSP )
• iText ( Version 2.1.7+ )
