A complete Go implementation of JOSE (JWA/JWE/JWK/JWS/JWT) for signing, encryption, and key management.
lestrrat-go/jwx is a comprehensive Go library implementing the full JOSE (Javascript Object Signing and Encryption) suite, including JWA, JWE, JWK, JWS, and JWT standards. It solves the problem of needing a complete, flexible toolset for handling JSON Web Tokens, cryptographic keys, and secure message formats beyond basic JWT parsing.
Go developers building secure APIs, authentication systems, or services that require complete JOSE compliance, including handling JWKs, JWE encryption, and complex JWS signatures.
Developers choose this library for its complete JOSE coverage, clean and consistent API design, and flexibility in handling custom claims and various serialization formats without requiring alternate structs.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements all JOSE specifications (JWA, JWE, JWK, JWS, JWT), including support for multiple signatures, detached payloads, and both compact/JSON serialization formats, as highlighted in the README.
Provides symmetric, consistent APIs like jws.Parse/Verify/Sign and jwe.Parse/Encrypt/Decrypt with explicit parameters and optional WithXXXX() options, making it easy to learn and use across different operations.
Works seamlessly with both JWK objects and raw key types (e.g., *rsa.PrivateKey), allowing for versatile key management without locking users into a specific format.
Includes jwk.Cache for automatic JWKS refresh, essential for production environments with key rotation, and is Bazel-ready for reproducible builds.
Supports parsing JWTs directly from HTTP request headers using jwt.ParseRequest, simplifying authentication in web applications without manual header handling.
Avoids open structs to protect users, but this design choice can limit direct access to internal data for advanced customization or debugging, as admitted in the README's philosophy section.
The extensive feature set adds unnecessary bloat for simple use cases like basic JWT validation, where lighter libraries might suffice and perform better.
The README strongly encourages migration from v0/v1 to v3, indicating potential instability and a steep learning curve for upgrades, which can disrupt existing projects.
Compared to more popular JWT libraries, it has a smaller community and fewer third-party integrations, which might limit support and tooling availability.
