## What it is
A Rust library for creating and decoding JSON Web Tokens (JWTs) in a strongly typed way, supporting HS256/384/512, RS256/384/512, PS256/384/512, ES256/384, and EdDSA algorithms. It offers pluggable crypto backends (aws_lc_rs or rust_crypto) and claim validation with serde-based typed claims.

## Use cases
- issue and verify JWTs in a Rust web API
- sign tokens with HS256 or RS256 in Rust
- validate JWT expiration and claims
- decode JWTs into typed structs with serde
- support EdDSA and ES256 token signing in Rust

## When to choose
- you need a mature, widely used JWT library in Rust with strong typing
- you need broad algorithm coverage including EdDSA and RSA-PSS
- you want pluggable crypto providers or custom JWT headers

## When to avoid
- you need a full auth server or session management, not just token encoding/decoding
- your project is not in Rust

## Facets
- artifact type: library
- maturity: active
- function: auth, serialization, cryptography
- domain: security, web-development, apis
- platform: rust
- tags: jwt, jsonwebtoken, token-validation, jwk, serde
