JWKS Endpoint Validator

Validate JSON Web Key Set (JWKS) endpoints and JSON documents to ensure they meet OAuth 2.0 and OpenID Connect standards.

What is JWKS?

A JSON Web Key Set (JWKS) is a set of keys containing the public keys used to verify JSON Web Tokens (JWTs) issued by an authorization server. It's commonly used in OAuth 2.0 and OpenID Connect implementations.

Common Use Cases:

• JWT signature verification
• OAuth 2.0 token validation
• OpenID Connect discovery
• API authentication

Key Components:

• kty - Key type (RSA, EC, etc.)
• kid - Key identifier
• use - Key usage (sig, enc)
• alg - Algorithm

Step 1: Choose Input Method

Validate a JWKS endpoint URL or paste JSON directly

Use JSON input instead of endpoint URL

JWKS Endpoint URL

This tool validates JWKS endpoints by fetching the JWKS document from the specified URL and validating that the JWK (key) is valid. It also checks for common misconfigurations and provides feedback on what is incorrect according to standards.
