Is RC4 symmetric or asymmetric?
Understand the Problem
The question is asking whether the RC4 encryption method is symmetric or asymmetric. RC4 is a stream cipher known for its simplicity and speed, and it is classified as a symmetric encryption algorithm.
Answer
symmetric
RC4 is a symmetric key stream cipher.
Answer for screen readers
RC4 is a symmetric key stream cipher.
More Information
RC4, designed by Ron Rivest in 1987, is a symmetric stream cipher widely known for its simplicity and speed. However, its use has been discouraged due to vulnerabilities.
Tips
A common mistake is confusing symmetric and asymmetric algorithms. Remember that symmetric encryption uses the same key for both encryption and decryption.
