Encryption is used to protect data by performing which action on the data?

Explanation:
Encryption protects data by turning plaintext into ciphertext, scrambling the content so it becomes unreadable without the proper key. This transformation is what keeps information confidential, which is the core purpose of encryption. Verifying authenticity focuses on proving the source or integrity of data, not hiding its content. Routing via a gateway is about moving data through a network path, not securing it. Compressing data reduces size and doesn’t protect content. So encryption’s defining action is scrambling the data to conceal its meaning.
