JWKS Generator
Generate 2048-bit RSA key pairs, manage kid values, and create JWKS (JSON Web Key Sets)
containing public keys only. You can also sign RS256 JWTs using the generated private key, inspect the payload, and copy keys, JWKS, or tokens with a single click.
Keys are created locally and never uploaded anywhere.
The JWKS contains only the public key.
RS256 signature uses the generated private key.
JWKS & RSA Key Pair Generator
Instantly generate JSON Web Key Sets (JWKS) and RSA key pairs (public/private keys) directly within your browser.
This security tool is invaluable when mocking authentication servers adhering to OIDC (OpenID Connect) and OAuth 2.0. It saves you the hassle of running manual OpenSSL commands locally, allowing you to quickly set up token signing verification for your test endpoints.
