It provides a single function, `where()`, that returns the file path to a PEM-formatted certificate bundle, and can also be invoked from the command line. The package has no runtime dependencies and supports Python 3.7 through 3.14.\n\nThe package is explicitly positioned as a specialized alternative to certifi for scenarios where Microsoft's certificate store is specifically required\u2014notably in projects like signify that validate Windows signatures. The maintainers warn that Microsoft's CA program allows granular deprecation of individual CAs that certificate bundle files cannot represent, meaning the bundle may inadvertently trust certificates no longer trusted in their intended context. For most general-purpose use, certifi is recommended instead.","worth_installing":"Yes, but only if you specifically need Microsoft's CA bundle. For general HTTPS and certificate validation, use certifi instead. Install mscerts only when your application explicitly requires Microsoft's Root Certificate Authorities\u2014such as validating Windows signatures or in compliance-constrained environments. Be aware of the deprecation limitation documented in the package description."},"id":"mscerts","links":{"html":"https://skillfed.io/packages/mscerts","md":"https://skillfed.io/packages/mscerts.md","pypi":"https://pypi.org/project/mscerts/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-01","license_spdx":null,"license_treatment":"copyleft","name":"mscerts","python_support":"supports_current","summary":"Python package for providing Microsoft's CA Bundle."},"popularity":{"monthly_downloads":171531,"position":10362,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2026.7.1"}
