SHA-1 gives 160-bit secure hash. Let's assume that a successful brute force attack is possible by trying 2^(160/3) combinations. If we do a double hash (as is done in Encase tool for forensics), the input is the secure hash of the message and the output is also another secure hash. Comparing this with SHA-2 using 256 bits, we can say:
A) SHA-256 is stronger because it requires 2^(256/3) brute force combinations, while SHA-1 still needs 2^(160/3) combinations.
B) double SHA-1 is stronger because it requires twice the 2^(160/3) combinations.
C) double SHA-1 is stronger because it requires about 2^(160/3) X 2^(160/3) maximum combinations because for each broken first stage, there are 2^(160/3) brute force attempts may be needed.
D) they are roughly equal and there was no need for the 256 version.

The thickness of a part is to have an upper specification of 0.925 and a lower specification of 0.870 mm. the average of the process is currently 0.917 with a standard deviation of 0.005. determine the percentage of product above 0.93 mm.

Write a program that reads the file, then displays the average number of steps taken for each month. (the data is from a year that was not a leap year, so february has 28 days.) your program needs to use at least 3 functions not counting main and display the information in a neat well formatted fashion.
