Question

what does encryption do to data during online transactions? a. changes its color b. makes it publicly accessible c. transforms it into a secure format d. increases its size

Explanation:

Encryption is a process that takes data and converts it into a form (using algorithms) that is secure and can only be accessed by those with the decryption key. It has nothing to do with color (Option A is wrong), it does not make data publicly accessible (Option B is wrong as encryption is for security, not public access), and while there can be some minimal overhead in encrypted data size, the main purpose is not to increase size (Option D is incorrect). The core function is to transform data into a secure format.

Answer:

C. Transforms it into a secure format
