What Is The difference Between Steganography And Cryptography


Steganography is the art and science of hiding information by embedding messages within other, seemingly harmless messages.

More commonly, steganography is used to supplement encryption. An encrypted file may still hide information using steganography, so even if the encrypted file is deciphered, the hidden message is not seen.



Cryptography is the art of protecting information by encrypting it into an unreadable format, called cipher text. Only those who possess a secret key can decrypt the message into plain text. Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable.
