Which of the following options best describes the purpose of the DES Algorithm?

The DES Algorithm, or Data Encryption Standard, is primarily designed to securely scramble data using confidential encryption keys. Its main purpose is to ensure data confidentiality by transforming plaintext into an unintelligible format (ciphertext) that can only be read by someone who has the correct decryption key. This secure scrambling protects sensitive information from unauthorized access, making it critical in various applications where secure data transmission and storage are necessary.

Options that mention basic account information, user identity verification, or transaction history tracking do not capture the primary functionality of the DES Algorithm. While it may indirectly support secure transactions and aid in user authentication by protecting sensitive data, its core objective is focused on encryption rather than tracking or verifying identities. In summary, the option that describes the DES Algorithm accurately emphasizes its role in data encryption and security.
