COMPUTER FUNDAMENTALS

Detailed explanation-1: -One method of cryptography is symmetric cryptography (also known as secret key cryptography or private key cryptography). Symmetric cryptography is best suited for bulk encryption because it is much faster than asymmetric cryptography. With symmetric cryptography: Both parties share the same key (which is kept secret).

Detailed explanation-2: -Symmetric encryption is also called secret key encryption, and it uses just one key, called a shared secret, for both encrypting and decrypting.

Detailed explanation-3: -Examples of symmetric key cryptography include AES, DES, and 3DES. Key exchange protocols used to establish a shared encryption key include Diffie-Hellman (DH), elliptic curve (EC) and RSA.

Detailed explanation-4: -Shared key encryption uses one key to encrypt and decrypt messages. For shared key cryptography to work, the sender and the recipient of a message must both have the same key, which they must keep secret from everybody else.

Detailed explanation-5: -To put this in the simplest terms possible, symmetric encryption is a type of encryption that uses the same key to encrypt and decrypt data. Both the sender and the recipient have identical copies of the key, which they keep secret and don’t share with anyone.
