===============
|
|
:compact-option:
|
|
|
|
'pdf-simple-sign' is a simple PDF signer intended for documents produced by
|
|
the Cairo library. 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.
