The Real-Time Developer Engine
JSON Web Token (JWT) is an open standard (RFC 7519). SilenVault's Architect Pro acts as a two-way binding engine. Edit the token to see the JSON, or edit the JSON to instantly forge a new token.
1. Header
Dictates the crypto algorithm (e.g., HS256). Editing this box re-encodes the first segment of the JWT.
2. Payload
The core data (claims). Editing this box re-encodes the middle segment of the JWT.
3. Signature
Type a secret key to test validity, or use it to forge a brand new mathematically valid signature.
