Problem: For this question, assume that the passwords are not dictionary words. They are exactly 10 characters in length, and the users limited to the use of 95 printable ASCII characters. (Please show all steps while answering the questions below.)
Consider a cracker capable of computing 6.4 million hash values a second. How long will it take a hacker who has stolen the password file to crack all the passwords using brute force if the system isn't using any salt value?
How long will it take to crack the passwords if the system is using a unique salt for each user (stored as plaintext in the password file)? Show your work.
