Detailed explanation-1: -Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic data. The entities communicating via symmetric encryption must exchange the key so that it can be used in the decryption process.

Detailed explanation-2: -Symmetric ciphers, also referred to as secret key encryption, use a single key. The key is sometimes referred to as a shared secret because the sender or computing system doing the encryption must share the secret key with all entities authorized to decrypt the message.

Detailed explanation-3: -Symmetric encryption uses a private key to encrypt and decrypt an encrypted email. Asymmetric encryption uses the public key of the recipient to encrypt the message. Then, if the recipient wants to decrypt the message, the recipient will have to use their private key to decrypt.

Detailed explanation-4: -A symmetric encryption is any technique where the same key is used to both encrypt and decrypt the data. The Caesar Cipher is one of the simplest symmetric encryption techniques, and of course, one of the easiest to crack.
