Q: Examples of _____________ encryption methods include DES, RC4, and AES.
- symmetric
- weak
- asymmetric
- strong
Explanation: The encryption and decryption processes are both performed with the same key in symmetric encryption. Both the Data Encryption Standard (DES) and the Advanced Encryption Standard (AES) are examples of symmetric algorithms that carry widespread recognition. Although it is a symmetric stream cipher, RC4 is not as widely used as other symmetric stream ciphers since it has several known flaws.
