## Which statement describes asymmetric encryption algorithms?

- They include DES, 3DES, and AES.
- They have key lengths ranging from 80 to 256 bits.
- They are also called shared-secret key algorithms.
- They are relatively slow because they are based on difficult computational algorithms.

**Answers Explanation & Hints:**DES, 3DES, and AES are examples of symmetric encryption algorithms (also known as shared secret key algorithms). The usual key length for symmetric algorithms is 80-256 bits. Asymmetric algorithms are relatively slow because they are based on difficult computational algorithms.
