Rather than coupling OpenStack services directly to a specific key manager implementation, Castellan acts as a plugin-based gateway, allowing different backends to be swapped without changing application code.\n\nThe package depends on cryptography, python-barbicanclient, and several oslo libraries for configuration, logging, and context management. It uses stevedore for plugin discovery and keystoneauth1 for OpenStack authentication. This makes it suitable for OpenStack operators and developers building services that need to manage secrets securely without hard-coding a particular key manager choice.","worth_installing":"Yes, if you are building or operating OpenStack services that need key management. The package is actively maintained, has no known vulnerabilities, and provides genuine value by decoupling your code from a specific key manager. If you are not working within an OpenStack environment or do not need key manager abstraction, it is not relevant."},"id":"castellan","links":{"html":"https://skillfed.io/packages/castellan","md":"https://skillfed.io/packages/castellan.md","pypi":"https://pypi.org/project/castellan/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-10","license_spdx":null,"license_treatment":"permissive","name":"castellan","python_support":"supports_current","summary":"Generic Key Manager interface for OpenStack"},"popularity":{"monthly_downloads":132956,"position":11533,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"5.8.0"}
