Symmetric Algorithms
Symmetric algorithms are a type of encryption algorithm that use the same key for both encryption and decryption of data. In other words, the sender and receiver of a message share a secret key that is used to both encrypt and decrypt the message. Symmetric algorithms are generally faster and more efficient than asymmetric algorithms, which use different keys for encryption and decryption. However, the use of a single key means that symmetric algorithms are less secure than asymmetric algorithms, as anyone who gains access to the key can decrypt the message. Common examples of symmetric algorithms include Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Blowfish.
