Chapter 2 – Cryptographic Tools TRUE/FALSE QUESTIONS: T F 1. Symmetric encryption is used primarily to provide confidentiality. T F 2. Two of the most important applications of public-key encryption are digital signatures and key management. T F 3. Cryptanalytic attacks try every possible key on a piece of ciphertext until an intelligible translation into plaintext is obtained. T F 4. The secret key is input to the encryption algorithm. T F 5. Triple DES tak...
