Tools for stamping and signing PDF files
The lack of open-source CLI tooling to handle digitally signing and stamping PDF files was bothering me, so I went ahead and rolled my own.
Note: The working title of this project (and former name of the repository on GitHub) was pdf-stamp
, which might still linger in some references.
Note: This project is currently in beta, and not yet production-ready.
The documentation for pyHanko is hosted on ReadTheDocs and includes information on CLI usage, library usage, and API reference documentation derived from inline docstrings.
PyHanko is hosted on PyPI,
and can be installed using pip
:
pip install 'pyHanko[pkcs11,image-support,opentype,xmp]'
Depending on your shell, you might have to leave off the quotes:
pip install pyHanko[pkcs11,image-support,opentype,xmp]
This pip
invocation includes the optional dependencies required for PKCS#11, image handling and
OpenType/TrueType support.
PyHanko requires Python 3.8 or later.
