pdf-simple-sign
===============
:compact-option:
'pdf-simple-sign' is a simple open source PDF signer intended for documents
generated by Cairo. As such, it currently comes with some restrictions:
* the document may not have any forms or signatures already, as they will be
overwitten
* the document may not employ cross-reference streams, or must constitute
a hybrid-reference file at least
* the document may not be newer than PDF 1.6 already, or it will get downgraded
to that version
* the signature may take at most 4 kilobytes as a compile-time limit,
which should be enough space even for one intermediate certificate
The signature is attached to the first page and has no appearance.
I don't aim to extend the functionality any further. The project is fairly
self-contained and it should be easy to grasp and change to suit to your needs.
