It parses and verifies these signatures to confirm software authenticity and detect tampering, making it a tool for security professionals and malware analysts who need to inspect code signatures outside their normal Windows ecosystem.\n\nThe library depends on cryptographic and certificate validation packages (certvalidator, asn1crypto, oscrypto, mscerts, typing_extensions) to handle the low-level signature verification. It supports PE executables (.exe, .dll), MSI files, catalog files (.stl, .cat), and any file signed through a catalog. Installation is straightforward via pip, with optional full support for additional file types.","worth_installing":"Yes, if you need to validate Windows Authenticode signatures outside the Windows ecosystem or in automated security workflows. The low install friction, MIT license, and active maintenance make it a practical choice for security professionals and malware analysts. The aging status (226 days since release) suggests slower development pace but not abandonment; verify that its cryptographic dependencies remain current for your threat model."},"id":"signify","links":{"html":"https://skillfed.io/packages/signify","md":"https://skillfed.io/packages/signify.md","pypi":"https://pypi.org/project/signify/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-12-31","license_spdx":"MIT","license_treatment":"permissive","name":"signify","python_support":"supports_current","summary":"Module to generate and verify PE signatures"},"popularity":{"monthly_downloads":111575,"position":12410,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.9.2"}
