Chapter 8, Problem 1CEDQ
Program Plan Intro
Brute-force attack:
It is a method to attack the encrypted data such as passwords or DES key until the data is decoded. This attack attempted by the combination of letters, symbols, and numbers to find the password and it requires more time when the password is too long.

Was Charlie exaggerating when he told Peter that cracking the encryption key with a brute force attack would take a long time?
Respond to the following in a minimum of 175 words:
Discuss a cryptography attack scenario. Choose an attack and explain how it works. Be sure to choose one that hasn’t been mentioned by another classmate. What countermeasures would you apply? How do the countermeasures you would use compare to those your classmates recommended for the attacks they chose? What do those similarities or differences tell you about fighting these types of attacks?
Was Charlie overestimating the amount of time it would take to crack the encryption key using a brute force assault when he offered Peter an estimate of how long it would take?
