@Lucian What's the constant string? Where can I get it?

@Lucian Any updates on the script you are making?

[Worcestershire]

@Lucian I've taken a stab at making my own script but to no avail. not sure exactly what's wrong, as every 'if' statement seems to match. Guess I'll wait to see your solution cuz now I'm hella curious as to how the hell they calculate the codes.

This method is hella confusing(most likely on purpose). My interpretation is: they use hash256 to hash '{fixed_value}{dd/mm/yyy}#{user_name}{salt}', and since thecall this value hash64 I assumed they encode it in base64;
Then iterate over the hash64 prepending only the digits, thus reversing the order;
If length = 5 they prepend the month in 'mm' format,else if 4 <= length(?) they rerun the function one more time, this time hashing '{fixed_value}{dd/mm/yyy}#{user_name+user_name}{salt+salt}' and again, if length = 5 prepend month in 'mm' format, if not return the code, the generated code is trimmed to 6 digits.

This is probably wrong, but this is the best I could do reading the code you gave

[Worcestershire]

Well, I give up XD Anyone wants the python code I created so far here it is, it doesn't seem to generate valid codes and I can't seem to figure out why. I tried to keep the structure as similar to the decompiled code as I could.

import datetime, calendar, hashlib, base64
PRE_SEED = '7oXtAXHz'

def get_date():
    now = datetime.datetime.now()
    last_day = calendar.monthrange(now.year, now.month)[1]  
    date = datetime.date(now.year, now.month, last_day)
    return date

def generate_code(name : str, date : datetime.datetime, is_spicy : bool, is_retry : bool):
    hash_key = "bundabunda" if is_retry and is_spicy else \
    "mikumiku"   if is_retry and not is_spicy else \
    "bunda"      if not is_retry and is_spicy else \
    "miku"
        
    formatted_date = date.strftime('%d/%m/%Y')

    code_key = f'{PRE_SEED}{formatted_date}#{name}{hash_key}'.encode('utf-8')
    hash64 = hashlib.sha256(code_key).hexdigest() 
    final_code = b''
    for ch in hash64:
        if ch.isdigit():
            final_code = ch+final_code


    

    if len(final_code) == 5: #This is weird because the chances of actuallt extracting 5 digits from the hash is nearly zero
         final_code = f'{date.strftime("%m")}{final_code}'
    if not is_retry and len(final_code) >= 4:
        return generate_code(name * 2,date,is_spicy,True)
        
    return final_code[:6]

def main():
    player_name = input('Nome no VRChat: ')
    date = get_date()
    premium_code = generate_code(name=player_name,date=date,is_spicy=False,is_retry=False)
    spicy_code = generate_code(name=player_name,date=date,is_spicy=True,is_retry=False)
    print(f'Senha: {premium_code}\nSpicy: {spicy_code}')

if __name__ == '__main__':
    main()

[Lucian]

@Worcestershire yeah, i am currently working on getting a better outcome on the script.

So far, I am getting the exact code within vrchat, but unable to replicate it within python env.

So I got an idea, I am going to use the file structures instead so it will utilize the udonsharp code directly.

it might take a few days

[NightFallen4You]

best of luck to you - even if it doesn't work, we're all grateful for the effort

[Worcestershire]

@Lucian I'm actually really curious about what's the discrepancy. looking forward to your code. Good Luck

[RoseVelvette]

Bump for number code please I need it

[Skeeboo]

I believe in y'all o7

[Layui]

someone is selling the codes on discord already so it's possible.
only the persistence does not work so you need to put the code always in.

[Worcestershire]

@Lucian Any progress? couldn't get my python script to work so I gave up.

[RedCob]

I'm suspecting that they're using a nonstandard SHA256-UTF8 implementation. @Lucian Is there a way for you to obtain the Udon implementation of the hashing algorithm?

[Worcestershire]

@RedCob If my reading of the code @Lucian pasted here is correct they're using the vrchat-udon-hashlib. Both call the lib using "_hashLibrary".

Here's the code of the hashing it uses if it's of any help:

[RoseVelvette]

@Worcestershire im sorry but what kind of coding is that??

is there a simple number code to put in the key pad in nero VIP mmd world??

[Worcestershire]

@VelvetteCakeYT not unless someone programs a code generator ¯\_(ツ)_/¯
The code is generated based on your VRChat user, so there won't be a simple code to put in the keypad.

[RoseVelvette]

@Worcestershire if people sub to nero patreon will they get the simple number code to put on key pad?

[Gamerfart9000]

@VelvetteCakeYT yea

[RoseVelvette]

@Gamerfart9000 do you need to pay to sub to nero patreon to get simple number code?

can someone with patreon account just give us the number code instead

[Snaggletooth]

There is no simple code. Each person has a different code. It is based on your name. When you sub to the patreon, you can be given your specific code.

That is why people are trying to figure out how it is generated. There have not been simple codes for 12 days, it is unlikely there will be simple codes again. If I were to give you my code, it would not work for you. If you were to give me yours, it would not work for me.
