This is ascii <-> shellcode encode / decoder tool

programmer : gunslinger_ <yudha.gunslinger[at]gmail.com>

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 !
