OAuth-Sheriff is a comprehensive Java library for validating JWT tokens in multi-issuer environments, designed for microservice architectures that need to validate tokens from multiple identity providers without making synchronous calls to authorization servers. The library focuses on offline validation with automatic JWKS key management, OpenID Connect Discovery for automatic configuration, and robust security features, making it ideal for developers building secure microservices that need to handle tokens from providers like Keycloak, Auth0, or Azure AD.
