## What it is
A zero-dependency .NET library implementing the full JOSE suite: JWT generation/decoding, JWE encryption, JWS signatures, and JWK key handling. It supports the complete JSON Web Algorithms set, is FIPS compliant, and is cross-tested against major JOSE libraries in other languages.

## Use cases
- issue and validate jwt tokens in .net
- encrypt payloads with jwe
- sign tokens with jws algorithms
- handle json web keys jwk
- implement openid connect / oauth2 token flows
- fips-compliant jwt processing
- decode jwt tokens without dependencies

## When to choose
- you need full JOSE/JWE/JWS/JWK support in .NET or .NET Core
- you want a minimal library with zero external dependencies
- FIPS compliance is required
- you need interoperability with jose4j, Nimbus-JOSE-JWT, or json-jwt
- you need cross-platform crypto including Linux/OSX ECDH support

## When to avoid
- you need a full identity/authorization server rather than a token library
- your project is not on .NET
- you need opinionated JWT middleware with built-in framework integration

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security, serialization, auth, json
- domain: security, apis, developer-tools, backend
- platform: dotnet, cross-platform, windows
- tags: jwt, jose, jwe, jws, jwk, openid-connect, oauth2, fips-compliant, zero-dependency, token-encryption, linux, macos
