Key Stretching correct answer: -A cryptographic technique that makes a weak key stronger by increasing the time it takes to test each possible key. In key stretching, the original key is fed into an algorithm to produce an enhanced key, which should be at least 128 bits for effectiveness. -Systems that use key stretching include Pretty Good Privacy (PGP), GNU Privacy Guard (GPG), Wi-Fi Protected Access (WPA), and WPA2. Widely used password key stretching algorithms include Password-Based Key D...
