Hai! Today we would discuss about the differences between steganography and cryptography. You may refer this previous posting as a brief introduction to Steganography.
Okay! how about Cryptography?
Cryptography was popular with the jargon text which is only can be conceal with its secret key. Only the one that can break the secret key and resolve the jargon text into a readable message can have the secret message.
In this case, the jargon text which is unreadable text such as ” hfuiafuwefhw” for example is call a ciphertext. They was publicly exposed to everybody during transmission or communication. Which create suspicious and this make anyone would like to decode it. If we compare it with the text steganography, the message is readable and unsuspicious. Since everyone can read, encoding text in neutral sentences is doubly effective. Only receiver know what the secret message written.
Ok now, I give a clearly example. You as the receiver, I give this key as a clue to conceal the secret text message. In the above paragraph, I did a simple text steganography.
Clue: In the fifth sentence. Combine each 1st letter to create a secret sentence.
Answer:
Fifth sentence:
Since everyone can read, encoding text in neutral sentences is doubly effective.
Combine each 1st letter to create a secret sentence.
Since everyone can read, encoding text in neutral sentences is doubly effective.
secret inside
This is the simplest way to explain what is steganography and the difference between cyrptography.
There was much more interesting information I would like to share with. Stay tune with my next posting.
