WARNING

The following is only working for GD 2.1 and before, as RobTop changed the GJP encoding to an actual hash called GJP2 and GJPs in their original version are no longer used in 2.2

What is Geometry Dash GJP ?

GJP is for "Geometry Jump Password". To generate GJP from user password, you need :

1. The password as string
2. Encipher it with XOR with key "37526"
3. Encode it with Base64 with URLSafe

Here is a Python function to generate GJP:

import base64
import itertools

def base64_encode(string: str) -> str:
    return base64.urlsafe_b64encode(string.encode()).decode()

def xor_cipher(string: str, key: str) -> str:
    return ("").join(chr(ord(x) ^ ord(y)) for x, y in zip(string, itertools.cycle(key)))

def generate_gjp(password: str):
    gjp = xor_cipher(password, "37526")
    gjp = base64_encode(gjp)
    return gjp

pw = input('GD Password (will be echoed) : ')
gjp = generate_gjp(pw)
print('GJP is : ' + gjp)

This repo is only to learn you what is GJP and how to generate it. Because here is no many sites that learn you that. Enjoy generating GJP !
