Example
JSON Web Key Set Viewer
Sample: JWKS with 1 RSA key
Example shown — replace it with your own JWKS JSON.
{ "keys": [{ "kty": "RSA", "kid": "a1b2c3", "use": "sig", "alg": "RS256", "n": "...", "e": "AQAB" }] } Result
How it works
- Paste your JWKS JSON.
- Each key's fields are parsed out.
- See a readable summary of every key's ID, type, and use.
The method
The JWKS JSON is parsed and each key's core fields — key ID, type, intended use, and algorithm — are summarized in a readable list.
FAQ
What is a JWKS?
A JSON Web Key Set, a standard format for publishing a set of cryptographic keys — commonly used by identity providers to publish the public keys needed to verify JWT signatures.
What do the "kid" and "alg" fields mean?
"kid" is the key ID, used to match a specific key when multiple keys are published; "alg" is the signing algorithm the key is intended to be used with, like RS256.
Does this validate a JWT against the keys?
No — this only parses and displays the keys in a JWKS for readability; JWT validation against a specific key is a separate step.
How we compare
| Feature | Online Tool Store | Raw JSON in a text editor | Full JWT debugging tool |
|---|---|---|---|
| No software install | Yes | Yes | No |
| Quick to start | Yes | Fast but hard to scan | Setup required |
| Free to use | Yes | Free | Often paid |
For a quick scan of a JWKS's keys without parsing raw JSON by eye, this is faster to read.
