#### JWTop

**JWTop** is a fast, developer-friendly JWT operations toolkit for the terminal. Decode, verify, create, sign, crack, and exploit JSON Web Tokens with a single CLI.

**Features**

* Decode and pretty-print any JWT without verifying the signature
* Verify signatures with HMAC secrets, RSA/ECDSA PEM keys, or JWKS endpoints
* Create and sign new tokens with custom claims, expiration, and issuer
* Re-sign existing tokens with a new algorithm or key
* Dictionary-attack weak HMAC secrets with built-in or custom wordlists
* Probe a live server for JWT vulnerabilities and report which exploits succeed

**Supported exploit techniques**

* `alg=none` bypass (all capitalisation variants)
* Blank secret and null signature attacks
* HMAC confusion (RSA/ECDSA public key used as HMAC secret)
* `kid` header injection (SQL injection, path traversal, raw)

**Supported algorithms**

* HMAC: HS256, HS384, HS512
* RSA: RS256, RS384, RS512
* RSA-PSS: PS256, PS384, PS512
* ECDSA: ES256, ES384, ES512

*The `exploit` and `crack` commands are intended for authorised security testing, penetration testing, CTF competitions, and educational purposes only. Never test systems you do not own or have explicit written permission to test.*
