## Security Testing Scripts for JWT
---
## jwt-cracker.py
JWT password/secret cracker.
```
$python3 jwt-cracker.py -jwt "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqd3QiOiJwd24ifQ.4pOAm1W4SHUoOgSrc8D-J1YqLEv9ypAApz27nfYP5L4" -t 10 -w /pentest/wordlist.txt
[info] Loaded wordlist.
[info] starting brute-forcing.
[#] KEY FOUND: 1234
```
---
## go-jwt-cracker
JWT password/secret cracker that is much faster.
```
$ cd go-jwt-cracker
$ go get
$ go build # Building the binary.
$ ./go-jwt-cracker -wordlist /pentest/wordlist.txt -token "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqd3QiOiJwd24ifQ.4pOAm1W4SHUoOgSrc8D-J1YqLEv9ypAApz27nfYP5L4"
[+] Key Found: 1234
```

## jwt-decoder.py
Decodes the value of JWT.
```
$ python3 jwt-decoder.py "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqd3QiOiJwd24ifQ.4pOAm1W4SHUoOgSrc8D-J1
YqLEv9ypAApz27nfYP5L4"
