Wrong encoding/decoding of default encryption password

[ajpallares]

Hello,

I found an issue in the code of SDOSEnvironment when using the -b flag in the SDOSEnvironment Build Phases script. The problem seems to be that the function generateDefaultPassword() returns an empty string, what causes a crash in the RNCryptor dependency.

This is the code where the error occurs:

private func generateDefaultPassword(bundle: Bundle = Bundle.main) -> String {
     let bundle = bundle.bundleIdentifier
     var password = ""
     var bytes = [UInt8]()
     if let bundle = bundle {
         let characters = Array(bundle)
         characters.forEach { (character) in
             var char = character.asciiValue ?? 0
             char += 7
             bytes.append(char)
         }
     }
     if let string = String(bytes: bytes, encoding: .utf8) {
         password = string
     }
        
     return password
 }

I believe the problem is that this code encodes using ascii but decodes using utf8. Changing the utf8 decoding to ascii should resolve the problem but I am not sure whether this is the intended behaviour.

Thanks!

Thanks for the notify.
Can you provide an example for the -b flag that produce this error?
I'll check this error ASAP
