Python PDF Signer

Create an invisible digital signature on a PDF file using Python CLI script.

Supports KIR SZAFIR Qualified Signature. Should work with any PKCS#11 card with up to few minor modifications.

Installation

Note about Windows: You need to install Build Tools for Visual Studio, which may be obtained from the Download Visual Studio Tools page -> Tools for Visual Studio -> Build Tools for Visual Studio 2022 -> Download

1. Clone the repository.
2. Create an virtualenv and install the requirements from the requirements.txt.
3. Copy config.dist.py to config.py and set the PKCS#11 library path correctly.
4. (Only required to verify documents) Copy trust_roots.dist.pem to trust_roots.pem and add the necessary qualified roots if needed.

Signing

Run: python3 signcli.py <input_file>

This should produce a signature that is accepted by the 3rd party qualified signature validation software.

Validating

Run: python3 validatecli.py <input_file>

Note that this validation script would barely validate any documents that were not signed using this tool.
