JWT Validator
Decode and validate JSON Web Tokens against RFC 7519
..
Decoded and, if you choose to verify, checked entirely in your browser using the Web Crypto API — the token itself is never sent to any server. Verifying against a JWKS URL makes a direct browser fetch to that URL (not through our server) to retrieve the issuer's public keys.
Verify Signature
Provide the key material used to sign this token. Nothing here leaves your browser except an optional direct fetch to a JWKS URL you specify.
