HIDING

[ FIRST CHOOSE ANY 4 HEX NUMBERS I CHOOSE -> ]

[ FF ] [ D8 ] [ A0 ] [ E2 ]

• SECRET MSG = LOL

[ CONVERT YOUR SECRET MSG TO BINARY ]

echo -n "lol" | xxd -b

• LOL = 01101100 01101111 01101100

• 0 = ff
• 1 = d8
• w = a0
• x = e2

[ NOW OPEN YOUR EDITOR AND CREATE A COMBINATION OF "01" BINARY AND "WX" STRINGS ]

[ EACH LINE CONTAIN 16 CHARACTERS ]

• 01wx1011wxxw00wx
• wxxw011xw011wx11
• 011wxxw011wx00xw

[ SAVE YOUR FILE ]

[ AFTER SAVING REPLACE "0" WITH "FF" ,"1" WITH "D8" , "W" WITH "A0" ,"X" WITH "E2" ]

sed -i "s/0/ff/g" key.txt

sed -i "s/1/d8/g" key.txt

sed -i "s/w/a0/g" key.txt

sed -i "s/x/e2/g" key.txt

[ NOW COPY ALL HEX AND PASTE IT INTO NEW TXT FILE USING HEXEDIT ]

cat key.txt

touch secret.txt

hexedit --color secret.txt

UNHIDE

[ FIRST WE EXTRACT ALL HEX DATA TO NEW FILE ]

od -An -vtx1 secret.txt > new

cat new

[ NOW WE REPLACE "FF" WITH "0" ,"D8" WITH "1" , "A0" WITH "W" ,"E2" WITH "X" ]

sed -i "s/ff/0/g" new

sed -i "s/d8/1/g" new

sed -i "s/a0//g" new

sed -i "s/e2//g" new

[ AFTER REPLACING WE REMOVE EXTRA SPACES ]

sed -i 's/\s\+//g' new

[ AFTER REMOVING SPACES WE WILL REMOVE "\N" IN EVERY SINGLE LINE ]

tr -d "\n" < new > n

[ WE WILL THEN PLACE A SPACE AFTER EVERY 8 CHARACTERS ]

sed 's/.\{8\}/& /g' < n > final

[ NOW ITS TIME TO CONVERT BINARY TO STRING ]

cat final | perl -lape '$_=pack"(B8)*",@F'
