Recommendation

For API authentication, JWT with short-lived tokens and refresh rotation is the industry standard. Test tokens with our JWT Decoder and JWT Validator.

FAQ

What is rs256 vs rs384 jwt algorithm?

rs256 vs rs384 jwt algorithm is a common JWT authentication topic. This guide explains the concept with step-by-step instructions, code examples, and links to free decoder and validator tools.

Are JWT tools on this site free?

Yes. All 13 tools run client-side in your browser with no account required. Tokens are never uploaded to a server.

How do I debug JWT errors?

Use our JWT Decoder to inspect structure, JWT Validator to verify signatures, and JWT Debugger for claim-by-claim analysis and expiration warnings.

Is decoding the same as validating a JWT?

No. Decoding reads header and payload without proving authenticity. Always verify the signature before trusting claims in production.

Which JWT algorithm should I use?

Use RS256 or ES256 for public APIs and OAuth. HS256 is fine for internal services when you can protect the shared secret.
