Which statement describes the Software-Optimized Encryption Algorithm (SEAL)?
- It uses a 112-bit encryption key.
- It requires more CPU resources than software-based AES does.
- It is an example of an asymmetric algorithm.
- SEAL is a stream cipher.
Explanation: SEAL is a stream cipher that uses a 160-bit encryption key. It is a symmetric encryption algorithm that has a lower impact on the CPU resources compared to other software-based algorithms, such as software-based DES, 3DES, and AES.
