[python] Simple Encoder(variants of hex and base64) - mls577 - 07-05-2013
The other day I stumbled upon hackbar, a very nifty little addon for firefox:https://addons.mozilla.org/en-us/firefox/addon/hackbar/
I saw the encoding tab, and thought to myself why not try to give this a try in python? so I did, and here's the result:
Code:
#!/usr/bin/env/python3.1
#encoder.py
#mls577
#Shouts to haxme and #suidrewt
#imports
import sys
import binascii
import re
sys_argv = [] #text list
hex_list = [] #hex list
def main():
#argument check
if(len(sys.argv) < 2):
usage()
else:
for word in sys.argv:
sys_argv.append(word) #add text to list
sys_argv.pop(0) #remove first entry from list(program name)
string = " ".join(sys_argv) #convert list to one string
bytes = to_bytes(string) #convert to bytes
#hex
hex_word = to_hex(bytes)
hword_string = to_string(hex_word)
#base64
base64_word = to_base64(bytes) #convert to base64
bword_string = to_string(base64_word) #convert back to usable string
spaced_hex = re.findall("..", hword_string) #regex, add every two chars to a list
#check to see if more than one hex character, this is for proper formatting
if(len(hword_string) > 2):
print("\nhex no spaces: " + hword_string) #hex no spaces
print("\nhex with spaces: " + " ".join(spaced_hex)) #hex spaced
print("\nhex seperated by : " + ":".join(spaced_hex)) #hex seperated by a colon
print("\nhex seperated by % :" + "%" + "%".join(spaced_hex)) #hex seperated by percent sign
print("\nunicode escaped: " + "\\x" + "\\x".join(spaced_hex)) #unicode escaped for a shellcode format
print("\nbase64: " + bword_string) #base64
else:
print("\nhex: " + hword_string)
print("\nhex with % : " + "%" + hword_string)
print("\nhex unicode escaped: " + "\\x" + hword_string)
print("\nbase64: " + bword_string)
def usage():
print("usage: ./encode.py <string> ")
def to_bytes(string):
return string.encode() #converts string to bytes
def to_hex(bytes):
return binascii.hexlify(bytes) #convert to hex
def to_base64(bytes):
return binascii.b2a_base64(bytes) #convert to base
def to_string(string):
string = string.decode() #convert back to string from bytes
string = string.rstrip() #remove newline from string
return string
main()
