Envoy JWT and JWKS Validation Course

Learn how Envoy validates JWTs with JWKS, issuer, audience, expiry, and signature checks before traffic reaches product APIs.

Maintained by Vishal Anand.

JWT validation at Envoy lets teams reject invalid tokens before product APIs receive traffic. This course explains issuer, audience, expiry, signature checks, remote JWKS, key rotation, route policy, and when an external authorization service is still needed.
