Which statement about client-side encryption is true?

Client-side encryption involves the process where data is encrypted by the client (the user or application) prior to being sent to a storage service, such as Amazon S3. In this context, the statement that is true is that the customer knows the keys and algorithms.

This is important because client-side encryption puts control in the hands of the customer, meaning they are responsible for generating and managing the encryption keys. Consequently, they have the ability to decide which encryption algorithms to use and how those keys are handled. This enhances the security posture for sensitive data, as the customer ensures that only they have access to the keys required to decrypt the data.

By managing their own keys and the encryption process, customers can also implement their own policies and controls for key management, ensuring compliance with their organization's security requirements. This level of control is a significant benefit of using client-side encryption, as it empowers customers to maintain their privacy and security over their data while taking advantage of cloud services.
