Tutorial Ren'Py Save protection

[zekro]

So a variety of Renpy games when I throw a save into Saveeditor will then make that save completely unusable for me, I press on yes when it asks me if I trust the site but then it doesn't load the file, so how do I disable that?

hey zekro i have the same problem in some of the games i played.and was going to create a new thread to this issue until i found your post. well i have no solution to the problem yet but maybe i can put us one step closer to it...
cuz the saveeditor site gives u the solution itself after u upload a savefile which is save protected by ren´py. it says:

Spoiler: note

You don't have permission to view the spoiler content. Log in or register now.

i´ve tried this several times in various games and got the same results in the end. when changing the savetoken.py like quoted above the games always crash if restarted afterwards. so there r only 2 options left now.
1. the changes i did are correct but when saved end in some syntax error or a similar coding issue
2. i missunderstand the note from saveditor in general and the changes i did are just wrong

so maybe a kind and experienced pervert here whos good with coding can help us out and gives a better example how the save protection can be disabled by changing the savetoken.py file...txxx in advance!!

Hello Guys!

I checked the code for you and made a workaround.

Open savetoken.py from the renpy folder. Search for def verify_data

def verify_data(data, signatures, check_verifying=True):
    """
    Verifies that `data` has been signed by the keys in `signatures`.
    """

    for i in signatures.splitlines():
        kind, key, sig = decode_line(i)

        if kind == "signature":

            if key is None:
                continue

            if check_verifying and key not in verifying_keys:
                continue

            try:
                vk = ecdsa.VerifyingKey.from_der(key)
                if vk.verify(sig, data):
                    return True
            except Exception:
                continue

    return False #You have to change this to True

In this method the program is verify the save file. You need to change the return in the end of the code.
Set it True and save the file and restart the game.

Now you can load any save file.
