Question 1 of 30
A financial institution is implementing a new data encryption strategy to protect sensitive customer information. They decide to use a symmetric encryption algorithm with a key length of 256 bits. If the institution encrypts a file containing 1,000,000 bytes of customer data, how many bits of data will be generated after encryption, and what is the significance of the key length in terms of security?
8,000,000 bits; a longer key length increases security by making brute-force attacks more difficult.
1,000,000 bits; a longer key length has no significant impact on security.
256 bits; a longer key length decreases the encryption speed significantly.
2,000,000 bits; a longer key length is only relevant for asymmetric encryption.
