When selecting an encryption method for data that needs to remain confidential for a specific length of time, a technician should consider the following: A. The key length of the encryption algorithm: Longer key lengths generally provide stronger encryption and are more resistant to brute-force attacks. B. The encryption algorithm's longevity: It is important to choose an encryption algorithm that has been widely tested and proven to be secure over time. Avoid using algorithms that are known to have vulnerabilities or are no longer considered secure. C. A method of introducing entropy into key calculations: Entropy is randomness that is used to generate encryption keys. It is important to have a good source of entropy to ensure the strength of the encryption keys. D. The computational overhead of calculating the encryption key: Some encryption algorithms require more computational resources to generate encryption keys. It is important to consider the performance impact on the system when selecting an encryption method. By considering these factors, a technician can choose an encryption method that provides the necessary level of confidentiality for the required length of time.
