COMPUTER FUNDAMENTALS

Detailed explanation-1: -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. The formulas used to encode and decode messages are called encryption algorithms, or ciphers.

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: -Encryption vs cryptography: Cryptography is the science of concealing messages with a secret code. Encryption is the way to encrypt and decrypt data. The first is about studying methods to keep a message secret between two parties (like symmetric and asymmetric keys), and the second is about the process itself.

Detailed explanation-4: -Cryptography is a science of using mathematics to encrypt and decrypt data. Cryptography enables you to store sensitive information or transmit it across insecure network.

Detailed explanation-5: -Cryptography can ensure the confidentiality and integrity of both data in transit as well as data at rest. It can also authenticate senders and recipients to one another and protect against repudiation.
