Explanation
Encryption (D) is the process of converting plain text into cipher text using an algorithm and key, making data unreadable to unauthorized parties - this is its exact definition.
Why the distractors are wrong:
- A. Steganography hides the existence of a message (e.g., concealing text inside an image), not scrambling its content.
- B. Encapsulation is a networking concept where data is wrapped with protocol headers as it moves down the OSI model - unrelated to text transformation.
- C. Decryption is the reverse process - converting cipher text back into plain text.
Memory tip: Think "Encrypt = Encode into secrecy" - the "en-" prefix means into, so encryption puts your data into a locked (crypted) state. Decryption is the key that lets you out.
