Explanation:Symmetric encryption is a cryptographic technique where the same key is used for both encrypting and decrypting data. This method is efficient and fast, making it suitable for large volumes of data. The sender and receiver must securely share the same secret key to use symmetric encryption. Popular symmetric encryption algorithms include AES (Advanced Encryption…
