What is Cryptography?
Cryptography means secret writing. In cryptography, the sender does not send a message directly to the receiver, before sending information to the receiver information or plain text is converted into cipher text by using some encryption algorithm then sent to the receiver and the receiver decrypts the cipher text into plain text to read the original information. It is of two types:
Difference between Steganography and Cryptography
Steganography and cryptography are critical components of network security. Network security has emerged as an essential part of today’s communication infrastructure. There was an urgent need for network security to protect confidentiality and data integrity. It protects the user against unauthorized access. Steganography hides communication traces, while cryptography uses encryption to make the message unreadable.
