Which process makes data difficult to read without appropriate knowledge?

Which process makes data difficult to read without appropriate knowledge?

• A. Decryption
• B. Ciphers
• C. Plain text
• D. Encryption

Answer: (D)

Encryption is the process that makes data unreadable unless you have the key. It transforms readable data (plaintext) into ciphertext using an algorithm and a key, so someone without the proper key (and often without knowledge of the algorithm) cannot turn it back into readable form. Decryption is the reverse, restoring the original text once you possess the correct key. A cipher refers to the specific method or algorithm used to perform encryption, but the act that creates the unreadable form is encryption itself. Plain text is simply data in readable form.
