Source code for encrypt.exe #9

Where does encrypt.exe come from? Trying to decrypt a firmware on ppc64 Linux...

Ran into the same issue and made a quick-and-dirty workaround using Wine. That means it will only work on architectures that support Wine but I guess that's better than nothing (or installing Windows).

Create a file called 'encrypt' in the root of the repository with the following contents:

#!/bin/bash

wine encrypt.exe "$@"

Save it and make it executable (chmod +x encrypt)

Patch bkutils/unpackager.py line 46 to say this:

        os.system("./encrypt "+destfile+"  510fb093 a3cbeadc 5993a17e c7adeb03 10000")

Unpackaging should now work.
