## Description

Build, decode and verify JSON Web Tokens on the go. Now with editable signature keys: paste your own secret or public key and check any token in seconds.

JSON Web Token is the fastest way to build, decode and verify JWTs on iPhone, iPad and Mac.

Paste any token and instantly see its header and payload, neatly typed and editable. Sign your own tokens with the algorithm of your choice, verify signatures against your own keys, and copy the result with one tap.

BUILD
• Create tokens from scratch with editable header and payload fields
• 12 signing algorithms: HS256/384/512, RS256/384/512, PS256/384/512, ES256/384/512
• One-tap generation of real random keys for every algorithm family

VERIFY
• Paste your own HMAC secret or public key to verify any token
• Clear verified/invalid signature badge
• Tamper with the payload and watch the signature react

INSPECT
• Typed values: strings, numbers, booleans, arrays, nested objects, null
• JSON view with configurable indentation, ready to copy
• Header and payload sizes in bytes
• Date helper to convert timestamps for iat, exp and nbf claims

Built for developers: no account, no tracking, everything stays on your device.
