What type of encryption involves the application or service encrypting data when it reaches its destination?

The correct answer pertains to server-side encryption, which is characterized by the application or service handling encryption processes once data has arrived at its storage location. This means that the data is encrypted by the server before it is stored, and often the decryption is also managed at the server level when data is accessed or used. This encryption approach primarily ensures that data is protected while at rest within the server's storage infrastructure.

This method is especially relevant in scenarios where an organization does not control the infrastructure but still needs to secure sensitive data. It allows for seamless integration with various services, enabling protection without requiring any action from the client application. The server manages the lifecycle of encryption keys, enhancing ease of use.

In contrast, other encryption methods like client-side encryption, database encryption, or end-to-end encryption operate differently, focusing on protecting data at the point of origin (client-side), specifically within a database management context, or ensuring that data remains encrypted between two endpoints throughout its transmission, respectively.
