It uses ctypes to call system USB HID APIs directly, avoiding the need for platform-specific compiled libraries. The library implements a U2F stack for signing authentication challenges and supports pluggable authenticators via the SK_SIGNING_PLUGIN environment variable.\n\nThe package is no longer maintained; its repository is archived and the authors explicitly recommend migrating to python-fido2, which supports the newer FIDO2 standard and provides backward-compatible U2F support. U2F itself is considered an outdated FIDO specification. If you are starting a new project, this library should not be your first choice.","worth_installing":"No. The package is abandoned, its repository archived, and the maintainers explicitly recommend python-fido2 instead. U2F is an outdated FIDO spec. Install only if you must maintain legacy code already using pyu2f; for new projects, use python-fido2."},"id":"pyu2f","links":{"html":"https://skillfed.io/packages/pyu2f","md":"https://skillfed.io/packages/pyu2f.md","pypi":"https://pypi.org/project/pyu2f/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2020-10-30","license_spdx":null,"license_treatment":"permissive","name":"pyu2f","python_support":"unspecified","summary":"U2F host library for interacting with a U2F device over USB."},"popularity":{"monthly_downloads":442599,"position":6634,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.5"}
