pdf-simple-sign
===============

'pdf-simple-sign' is a simple PDF signer intended for documents produced by
the Cairo library (≤ 1.17.4 or using PDF 1.4), GNU troff, ImageMagick,
or similar.

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.

Packages
--------
Regular releases are sporadic.  git master should be stable enough.
You can get a package with the latest development version using Arch Linux's
https://aur.archlinux.org/packages/pdf-simple-sign-git[AUR],
or as a https://git.janouch.name/p/nixexprs[Nix derivation].

Documentation
-------------
See the link:pdf-simple-sign.adoc[man page] for information about usage.
The rest of this README will concern itself with externalities.

Building
--------
Build dependencies: Meson, Asciidoctor, a C++11 compiler, pkg-config +
Runtime dependencies: libcrypto (OpenSSL 1.1 API)

 $ git clone https://git.janouch.name/p/pdf-simple-sign.git
 $ cd pdf-simple-sign

In addition to the C++ version, also included is a native Go port:

And a crude external VFS for Midnight Commander, that may be used to extract
all streams from a given PDF file:
