CompTIA Security+ (SY0-601) — Question 619

Which of the following best describes the process of adding a secret value to extend the length of stored passwords?

Answer options

• A. Hashing
• B. Quantum communications
• C. Salting
• D. Perfect forward secrecy

Correct answer: C

Explanation

Salting is the process that involves adding a unique value to each password before hashing, which helps prevent attacks such as rainbow tables. Hashing itself transforms the password into a fixed-length string but does not involve adding extra data. Quantum communications and Perfect forward secrecy are unrelated concepts that deal with secure communication rather than password storage.
