Detailed explanation-1: -Cryptography is an art of writing a secret code that defend the data getting exchanged between two communicating parties from external attack. Cryptography is used to hide the confidential details so that the information can be sent securely over the timid network.

Detailed explanation-2: -Cryptography is the art and science of making a cryptosystem that is capable of providing information security. Cryptography deals with the actual securing of digital data. It refers to the design of mechanisms based on mathematical algorithms that provide fundamental information security services.

Detailed explanation-3: -Encryption is the process of scrambling data so that it is unreadable to anyone except those who possess a key that decrypts the data. Decryption is the process of restoring data from its encrypted form.

Detailed explanation-4: -Cryptography, the Science of Secret Writing.

Detailed explanation-5: -Cryptography is the science and art of secret writing-keeping information secret. [1] When applied in a computing environment, cryptography can protect data against unauthorized disclosure; it can authenticate the identity of a user or program requesting service; and it can disclose unauthorized tampering.
