Symmetric ciphers are encryption techniques in which the same secret key is used for both encryption and decryption of data, making them one of the oldest and most widely used mechanisms in network security. They protect confidentiality by transforming plaintext into unreadable ciphertext using mathematical algorithms, ensuring that only authorized parties possessing the shared key can access the original information. Because the same key is used at both ends, secure key distribution becomes a critical challenge, especially in large or open networks where interception risks are high. Symmetric encryption is valued for its speed and efficiency, making it suitable for encrypting large
