About this Tool
Need to generate a JSON Web Token (JWT) for testing or development? Our JWT Encoder takes your raw JSON payload, encodes it, and signs it using the HS256 algorithm with your provided secret key. All processing happens entirely in volatile memory and is instantly discarded.
Frequently Asked Questions
Is my secret key safe?
Yes. The payload and secret key are processed entirely in server RAM to compute the signature and are immediately purged. We do not store or log any keys.
What algorithm is used to sign the token?
This tool currently uses the HMAC SHA-256 (HS256) algorithm to securely sign the generated JWT.
