ascii shellcode encoder decoder tool


#!/usr/bin/python
'''
	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 !
