Steganography whitespace using media plaintext

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos (στεγανός) meaning "covered or protected", and graphei (γραφή) meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.



Ok, when i was 21 yearsold, i had make some program like steganography. This program will hide secret message behind plainttext media. Plainttext media i mean are *.txt,*.xml, *.php,*.html, etc.

The techniques is:

1. Select media carier for hiding our secret messages
2. input our text message
3. input key for encrypting our message
4. compressing our message using huffman table (optional)
5. media carier with our secret message (cipher text)

Process decrypt is from step 5 to step 1 (reverse). to decrypt message, the receiver message must know the key for encrypting our secret message.

here is the screenshot of program:
