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. + +Building +-------- +Build dependencies: Meson, a C++11 compiler, pkg-config + +Runtime dependencies: libcrypto + + $ git clone https://github.com/pjanouch/pdf-simple-sign.git + $ cd pdf-simple-sign + $ meson builddir + $ cd builddir + $ ninja + +Usage +----- + + $ ./pdf-simple-sign document.pdf document.signed.pdf KeyAndCerts.p12 password + +Contributing and Support +------------------------ +Use this project's GitHub to report any bugs, request features, or submit pull +requests.
