Cryptography, or cryptology, is the art of concealing messages in order to keep them private or confidential.

When the message is encoded, only those who have been given the key or code book will know how to decode the secret message.

Steganography is the art of hiding the message with a "cover" so that what people see is the cover without realizing there is a secret message hidden within or under it.
