A unified Node.js API for password hashing algorithms like Argon2, PBKDF2, and bcrypt, simplifying secure password management.
upash is a Node.js library that provides a unified API for password hashing algorithms like Argon2, PBKDF2, scrypt, and bcrypt. It simplifies secure password management by offering a consistent interface, automatic algorithm detection, and easy migration between hashing methods. The project addresses the challenge of correctly implementing and maintaining password security in applications.
Node.js developers building applications that require secure password storage, such as web services, APIs, or authentication systems. It's particularly useful for teams that need to adhere to security best practices and plan for future algorithm upgrades.
Developers choose upash because it abstracts the complexity of different password hashing algorithms into a single, easy-to-use API. It reduces the risk of implementation errors, supports seamless algorithm migration, and follows the PHC string format for interoperability, making password security more maintainable and future-proof.
🔒Unified API for password hashing algorithms
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a single, consistent interface for all supported algorithms like Argon2 and bcrypt, simplifying code by abstracting away algorithm-specific details, as shown in the usage examples.
The verify function automatically selects the correct algorithm based on the hash identifier, making it easy to handle mixed hash types without manual intervention, as highlighted in the API.
Includes step-by-step guides and patterns for upgrading hashing algorithms without breaking existing user accounts, addressing a common pain point in password security maintenance.
All algorithms follow the Password Hashing Competition string format, ensuring standard interoperability and making hashes portable across systems that adhere to PHC.
The main algorithm implementations are native to Node.js, with browser-compatible versions marked as WIP, severely limiting use in frontend or cross-platform applications.
Requires installing upash plus separate packages for each hashing algorithm, adding complexity to setup and maintenance compared to all-in-one libraries.
The unified API layer introduces slight performance overhead compared to using algorithms directly, which might matter in high-throughput authentication systems.
