    This is ascii <-> shellcode encode / decoder tool
    programmer : gunslinger_
    This was written for educational purpose only. or fucking messing around...
    i.e how to use encode mode :
        --------------------------------------------------------------
        gunslinger@localhost:~/shellcode$ ./shellcodeencdec.py
        shellcode hex encode decoder
        programmer : gunslinger_
        what do you want to do ? encode / decode
        => encode
        Please input data : /bin
        shellcode => \x2f\x62\x69\x6e
        gunslinger@localhost:~/shellcode$
        --------------------------------------------------------------
    i.e how to use decode mode :
        "\x68\x2f\x2f\x73\x68"  // push   $0x68732f2f
        "\x68\x2f\x62\x69\x6e"  // push   $0x6e69622f
        we know 'x68' is push, so drop it...
        "\x2f\x2f\x73\x68"     $0x68732f2f
        "\x2f\x62\x69\x6e"     $0x6e69622f
        --------------------------------------------------------------
        gunslinger@localhost:~/shellcode$ ./shellcodeencdec.py
        shellcode hex encode decoder
        programmer : gunslinger_
        what do you want to do ? encode / decode
        => decode
        Please input data : \x2f\x2f\x73\x68
        hex       =>  2f2f7368
        plaintext => //sh
        gunslinger@localhost:~/shellcode$ ./shellcodeencdec.py
        shellcode hex encode decoder
        programmer : gunslinger_
        what do you want to do ? encode / decode
        => decode
        Please input data : \x2f\x62\x69\x6e
        hex       =>  2f62696e
        plaintext => /bin
        gunslinger@localhost:~/shellcode$
        --------------------------------------------------------------
        and we got that is "/bin//sh"

    warning ! this is not disassemble tool !
