This type of （ ） exploits the characteristics of the algorithm to attempt to deduce a specific plaintext or to deduce the key being used. If the attack succeeds in deducing the key, the effect is catastrophic: All future and past messages encrypted with that key are compromised. The second method, known as the （ ）-force attack, is to try every possible key on a piece of （ ） until an intelligible translation into plaintext is obtained.
