Stego 1

The original string of 0's and 1's from the image between "00 00":

0011100001100110011011101101000011000010111001100110110

This bit stream is only 55 bits! Its missing a 1 or 0 somewhere in there. I used this script to generate all possibilities of valid bitstreams:

#!/bin/bash
for EACH in `seq 1 51`
do
let NEXT=$EACH+1
#Stick in a 0
cat original | cut -c 1-$EACH | tr -d [:cntrl:]
echo -n 0
cat original | cut -c $NEXT-100 | tr -d [:cntrl:]
echo  00001101

#stick in a 1
cat original | cut -c 1-$EACH | tr -d [:cntrl:]
echo -n 1
cat original | cut -c $NEXT-100 | tr -d [:cntrl:]
echo 00001101 #Stick on a carrige return at the end
done

With all of these bit streams I use http://www.roubaixinteractive.com/PlayGround/Binary_Conversion/Binary_To_Text.asp

00111000001100110011011101101000011000010111001100110110

Is the correct binary stream, which is 837has6
