In this problem we explore the relationship between password length and cryptographic security.Suppose a password consists of 6 ASCII characters. You can review the ASCII characters here.. There are exactly 2'= 128 ASCIIcharacters; we will assume every character in the password is ASCII (non-printing characters are allowed).What is the size of the keyspace that consists of passwords of this form?What is the equivalent key length in bits?Assuming that you could check one password every 10-"seconds,what is the worst case running time for cracking this password by brute force search (in days)?|Now assumethat the user used only 28 characters from the keyboard. What is the key length in bits in this case?How manydays, in the worst case, would it take to break this weaker password? You can't round to the nearest day herebe as exact as possible.Supposing you used only 28 characters, how long is the shortest password that achieves 248 bits of security?
