L8W8JWT GUI is a graphical interface around l8w8jwt, a minimal and open-source JSON Web Token library written in C.
It is handy during development and when testing or implementing web services that deal with auth tokens. Features include:
• Encoding and signing tokens with the HS, RS, PS, ES and EdDSA algorithm families
• Setting standard claims such as issuer, subject, audience and expiry, plus custom claims
• Decoding tokens and verifying their signature and timestamps
• Generating RSA, ECDSA and Ed25519 key pairs, with extra entropy collected from your mouse
• Fully offline: the app has no network access
