Unlock the Power of Rust: Top 9 Authentication Libraries
Rust, a low-level language with high-level ergonomics, is revolutionizing the world of network and web applications with its speed, reliability, and support for asynchronous I/O. As data privacy concerns continue to grow, authentication and authorization have become crucial components of modern web development. Fortunately, Rust offers a wide range of high-quality, production-ready crates for authentication and authorization.
Evaluating the Top 9 Authentication Libraries
In this guide, we’ll explore nine stable, production-ready authentication libraries based on popularity, completeness, maintenance, and support for stable Rust. We’ll also preview some promising crates that aren’t yet production-ready but should be on your radar.
1. Cookie: A Foundation for Session-Based Authentication
Cookie is a production-ready crate for creating and parsing HTTP cookies, perfect for managing sessions, encrypting, and signing cookies. With thousands of downloads, it serves as a foundation for building session-based authentication strategies.
2. Jsonwebtoken: A Popular Choice for Authorization
Jsonwebtoken provides support for verifying and creating JWT tokens, making it a popular choice for authorization. With thousands of downloads and an active team of maintainers, it’s a highly stable and widely used library.
3. Oauth2: A Complete Implementation of the OAuth 2 Protocol
Oauth2 offers a complete implementation of the OAuth 2 protocol, supporting async and sync I/O, obtaining access tokens, verifying state, and obtaining refresh tokens. Its framework-agnostic design makes it compatible with various web frameworks.
4. Otpauth: One-Time Passwords Made Easy
Otpauth provides support for both HOTP and TOTP algorithms, making it easy to generate one-time passwords (OTPs). Its APIs are intuitive and feature full implementation of HOTP and TOTP.
5. Yup-oauth2: OAuth 2.0 for Server-to-Server Authentication
Yup-oauth2 offers an implementation of OAuth 2.0 for server-to-server authentication, making it perfect for implementing client libraries for different services. Its support for both service accounts and installed applications makes it a versatile choice.
6. Asap: Lightning-Fast Token Generation and Validation
Asap is an authentication mechanism created and maintained by Atlassian, supporting nonstandard claims and performing validation and token generation at incredible speeds. Its foundation on the jsonwebtoken crate ensures full support for ASAP specifications.
7. JWKS-Client: Validating JSON Web Tokens with Ease
JWKS-Client provides support for validating JSON web tokens using a JWKS (JSON web keyset), making it easy to verify tokens with symmetric signature validation. Its support for key caching and compatibility with various providers make it a valuable addition to any authentication strategy.
8. Openssl: A Rust Binding for the OpenSSL Library
Openssl is a Rust binding for the OpenSSL library, providing full support for signing tokens, hashing passwords, generating random auth tokens, and encrypting data. Many authentication libraries rely on OpenSSL for signing and hashing data.
9. Pgen: Generating Passphrases with Ease
Pgen generates passphrases using the EFF’s wordlists for random passphrases, making it a valuable tool for authentication.
Keeping an Eye on Upcoming Crates
While not yet production-ready, the following crates show promise and should be on your radar:
- Boringauth: A one-stop solution for any app’s authentication-related needs, supporting passphrase authentication and both HTOP- and TOTP-based authentication.
- Oxide-auth: An implementation of OAuth for the server, making it easy to manage OAuth tokens on the server.
- Frank JWT: A crate for verifying and generating JWT, capable of reading keys automatically from a path.
Summary
To summarize, here is a comprehensive table comparing the features, capabilities, and pros and cons of the Rust authentication libraries discussed in this guide.
