whitespace-steganography

Use HTML's interpretation of multiple spaces to hide base64 code on any HTML page.

Example:

wget -O - 'https://example.org/' | grep -E '\[[0-9]+\]' | sed 's/\s\s\s\s/1/g' | sed 's/\s\s\s/0/g' | sed -r 's/\[[0-9]+\]//g' | tr -d -c '10' | fold -w 6 | tr '\n' ' ' > binary.txt

bash binary-base64-tobefree.sh binary.txt | base64 -d > decoded-output.txt
