Detailed explanation-1: -Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.
Detailed explanation-2: -The study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek (kryptos), or hidden and (graphia), or writing. If you don’t know Greek (and not many of us do) the above letters could be a form of code themselves!
Detailed explanation-3: -Ciphers, also called encryption algorithms, are systems for encrypting and decrypting data. A cipher converts the original message, called plaintext, into ciphertext using a key to determine how it is done.
Detailed explanation-4: -Cryptography, at its most basic, is the science of using codes and ciphers to protect messages. Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message.
