Embed / attach any type of file to a PDF.
Files can be embedded (attached) to the PDF so that they stay with the PDF. Any attachments you add to a PDF will move with it if you transfer the document to a new location or person.
Auto hyperlink generation
pdfMachine will automatically scan the text in a PDF creating hyperlinks when it finds particular
words
or phrases you have defined. This can be handy for common terms such as company names or
products.
e.g. You can setup pdfMachine so that whenever the word "pdfMachine" is
encounted in
a PDF, a hyperlink to www.pdfmachine.com is created.
Redaction
Use pdfMachine to redact (permanently remove) blocks of text and images from the PDF, replacing them with black blocks. The information is removed, not just hidden. Redaction provides a means to protect sensitive or confidential information.
Stamper
The stamper is a nice way to ask a user to fill out a form then have the results of that form "stamped" onto the PDF. Details here.
Split PDF into many PDFs
The Split PDF functionality allows you to split or 'explode' a PDF into smaller PDFs. You can split per page or per set number of pages. Details here.

What is a Time Stamp Authority (TSA) ?

a certain time.
