Need SB encryption key
I'm working on a project with slayerrobe7 that will make collabs easier, but i need help: i need the encrypion key for SBs so i can easily edit them with the program, and still run it in scratch. Does anyone have this?

I'm thinking Advanced Topics or Questions About Scratch.

Re: Need SB encryption key
I don't there's any encryption for SB files. It's more of just how the bytes are put to form the saved data... and there should be a Wiki about that.
Oh, as well as a couple AT threads about it

Re: Need SB encryption key
Doing what you want is kinda complicated. I made a little wiki collecting together all the information on the Scratch file format; it's similar to the link posted above, with some updates.
I have a Python library somewhere that should be able to do this (it still has a few quirks) -- I keep promising myself I'll upload it sometime...

Re: Need SB encryption key
I think i get it, i need to deserialize the .SB files. the problem is, I'm not working with squeak. Would it be possible to convert the objects to java?

Re: Need SB encryption key
i thought you could edit them using notepad rather easily - the only problem was that the scratch app wouldn't load the sb up again
TRocket need your help again

it's impossible to understand, although it is easy to edit.

Actually, the reason nobody figured it out was because the Scratch file is a mixture of ASCII and plain integer data. So Notepad and TextEdit try hard to decode the ASCII bit, and the plain int data is either shown as a special symbol, or hidden. Now when you edit and save in notepad or TextEdit, the hidden int bytes are omitted, and the file goes whacky in Scratch.
