Detailed explanation-1: -Symmetric encryption uses the same key to perform both encryption and decryption functions. Symmetric encryption uses a shared private key while asymmetric encryption uses a public/private key pair. Another difference between asymmetric and symmetric encryption is the length of the keys.
Detailed explanation-2: -A public key is also used to encrypt a message or check the legitimacy of a digital signature. It is accompanied by a corresponding private key, which is known only to its owner. Private keys are used to decrypt messages that were created with the corresponding public key or to create signatures.
Detailed explanation-3: -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-4: -A set of bits known as the secret key is used in secret key cryptography to decipher the plaintext message to be encrypted. The same key is employed to decipher the text message: that’s why it is also called a symmetric key.
