Suppose an offline dictionary attack is used, and suppose the attacker has prepared a dictionary of 1000 entries, the password file contains 500 users ' hashed passwords with 500 different salt values(Salt values correlation to user accounts is unknown to the attacker). If the attacker's goal is to crack as many passwords as possible. Calculate how many hash values would the attacker compute in the worst case (final answer)? Answer:

Write a program to read the data from the file and produce the average temperature and average humidity for all the records in the file. This is a very large file - it is the actual temperature and humidity data from our server room. You would spend hours trying to do this manually, with a calculator, and you likely would make mistakes along the way. This is where computers are far superior to humans when dealing with boring, repetitive tasks. The output of the program will look like this: Average Temperature (C): NN.NNNNNNNNNNNNNN Average Humidity (%):…
