It handles signing, stamping, and validating PDF signatures according to standards like PAdES, and supports hardware tokens via PKCS#11. The library depends on cryptography, lxml, requests, and certificate validation tools to perform its core operations.\n\nThe package is designed for developers who need to integrate PDF signing into Python applications. It requires Python 3.10 or later and offers optional features for image handling, QR codes, and OpenType font support. The CLI functionality has been separated into a standalone package (pyhanko-cli), so this distribution focuses purely on the library API.","worth_installing":"Yes. Active maintenance, permissive MIT license, low install friction, no known vulnerabilities, and a focused scope make this a solid choice for PDF signature work. The separation of CLI into a separate package keeps the library dependency footprint lean. Verify whether optional dependencies match your use case before installing."},"id":"pyhanko","links":{"html":"https://skillfed.io/packages/pyhanko","md":"https://skillfed.io/packages/pyhanko.md","pypi":"https://pypi.org/project/pyhanko/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-26","license_spdx":"MIT","license_treatment":"permissive","name":"pyHanko","python_support":"supports_current","summary":"Tools for stamping and signing PDF files"},"popularity":{"monthly_downloads":9006390,"position":1567,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.36.2"}
