Hey! Is there anyone here how knows how to decrypt Unicode?
As an exampel am I trying to decrypt the source code to robot unicorn attack which probaly is encoded in UTF-8.

As far as I know it isn't possible to encrypt, with a character encoding like unicode, anything; let alone a flash file. Unicode is just a way to interpret data values as characters, like ASCII.

As far as i can tell you are trying to decompile a flash game to edit values? You can use flasm, or flare to get a decompile. The difference between the two is that with flasm you can recompile the changed code. :ugeek:

It's similar with EXE files that are opened up in Notepad.

Thank you jgreen45. So an Unicode file cannot be encrypted? OKey... What is the meaning of "let alone" btw?

Unicode is just a way to read data a Character encoding, for instance over the internet the bits and bytes are sent to my computer. Since the internet has changed over the years different methods exist to read these bits in different ways. Unicode is one of these ways of interpreting data Windows-1252 is another. For instance HTS Forums use Unicode, you can see this in the source code:

Code: Select all
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />


Unicode is in no way a form of encryption. A file encoded (not encrypted) with Unicode can be encrypted just like any other file.

I use it normally in the terms of 'even less likely' but I don't think that's a dictionary definition. 8-)

Fash was referring to how, when you open an EXE file in notepad sometimes parts of it are readable as opposed to being a random garble of letters. You can change these values and still have a working .exe, with some modifications ;). Flasm is used to decompile a flash file into a human readable-ish text file you can edit, similar to Fash's example, but I doubt it works with a .exe.

I know what Unicodes is, and I know a bit of how to hex edit. My point was, that if I only use a specific plane of the Unicode "alphabete", (for example the Supplementary Multilingual Plane) and I know in which order the chars should be placed (the bidi-algoritm is made for that I think), I should technically be able to encrypt it.
But however, if this never is done in practise, you have given me all the answers I needed. Thx :)
