Symmetric cipher: A type of cipher that uses the same key for both encryption and decryption. It is a fundamental type of encryption technique that uses a single key to convert plaintext data into ciphertext, and the same key is used to convert the ciphertext back into the original plaintext. Examples of symmetric ciphers include DES (Data Encryption Standard), AES (Advanced Encryption Standard), and RC4. They are widely used due to their speed and efficiency but require secure key distribution and management.
