Description
  ``pyhanko`` is a library for working with signatures in PDF documents. **Note:** pyHanko's CLI is no longer bundled together with the library. This functionality is now distributed separately as ``pyhanko-cli``. ### Documentation The [documentation for pyHanko is hosted on ReadTheDocs](https://docs.pyhanko.eu/en/latest/) and includes information on CLI usage, library usage, and API reference documentation derived from inline docstrings. ### Installing PyHanko is hosted on [PyPI](https://pypi.org/project/pyHanko/), and can be installed using `pip`: ```bash pip install 'pyHanko[pkcs11,image-support,opentype,qr]' ``` Depending on your shell, you might have to leave off the quotes: ```bash pip install pyHanko[pkcs11,image-support,opentype,qr] ``` This `pip` invocation includes the optional dependencies required for PKCS#11, image handling, OpenType/TrueType support and QR code generation. PyHanko requires Python 3.10 or later.
