It provides a straightforward API for generating keypairs, signing messages, and verifying signatures, with support for both deterministic and randomized signing modes. The package has zero external dependencies, full type hints, and supports Python 3.9 through 3.14.\n\nThe library is designed for developers who need post-quantum-resistant digital signatures or want to experiment with hash-based cryptography. It offers both high-level convenience methods (like `sign_pure` and `verify_pure`) and low-level APIs for advanced use cases. Keypairs and secret keys can be exported and imported using standard PKCS formats, making it practical for integration into larger systems.","worth_installing":"Yes, if you need FIPS 205 digital signatures and want a dependency-free pure Python implementation. The package is actively maintained, well-typed, and supports current Python versions. However, verify whether the implementation has undergone formal security audit and whether performance meets your requirements before using in production systems with high-assurance security needs."},"id":"slh-dsa","links":{"html":"https://skillfed.io/packages/slh-dsa","md":"https://skillfed.io/packages/slh-dsa.md","pypi":"https://pypi.org/project/slh-dsa/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-31","license_spdx":null,"license_treatment":"copyleft","name":"SLH-DSA","python_support":"supports_current","summary":"Pure Python implementation of the SLH-DSA algorithm (based on FIPS 205)."},"popularity":{"monthly_downloads":161616,"position":10627,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.4"}
