Moreover, the first symbol must be English alphabetic lower case; the second symbol must be English alphabetic (either case) or numeric (0 - 9); and the third must be numeric. How many possible passwords can be specified based on these rules?

Fully explain your answers for all questions. Q1. A password must have exactly ten symbols, each symbol being one of the 26 lower case letters or one of the five special symbols as follows: *, &, %, $, #. (You can leave your answer as a mathematical expression rather than a number ). (a) How many such passwords are possible in total? (b) How many passwords are such that all their symbols are distinct? (c) How many passwords use only...

A system requires passwords be made up of upper and lower case letters, digits, and punctuation symbols. How many bits of entropy are in a 6 character password? A 12 character password? Suppose your password is three 6-character words, made up of only lowercase letters. How much entropy is in such a password???

Suppose that you open an email account and you are told that you need six-character password & the characters must be alpha-numeric ( either alphabetical or numerical). Assume that a lower case letter is different from an upper case one. a) How many passwords are possible? Give the exact answer and do not use scientific notation. Show some work. b) Suppose a computer hacker tries to guess what your password is by testing all possible passwords and it takes his...

C Program In this assignment you'll write a program that encrypts the alphabetic letters in a file using the Vigenère cipher. Your program will take two command line parameters containing the names of the file storing the encryption key and the file to be encrypted. The program must generate output to the console (terminal) screen as specified below. Command Line Parameters Your program must compile and run from the command line. The program executable must be named “vigenere” (all lower...

Two words or phrases in English are anagrams if their letters (and only their letters), rearranged, are the same. We assume that upper and lower case are indistinguishable, and punctuation and spaces don't count. Two phrases are anagrams if they contain exactly the same number of exactly the same letters, e.g., 3 A's, 0 B's, 2 C's, and so forth. Some examples and non-examples of regular anagrams: * The eyes / they see (yes) * moo / mo (no) *...

Another use of the transition matrix is in stochastic modeling. An example is the following: Imagine a park with three locations: a lake; a picnic area; and a playground. Every hour, on the hour, the parkgoers move according to the following rulcs: Half of those at the lake move to the picnic area, and one-quarter of those at the lake move to the playground. Half of those at the picnic area go to the lake, and the other...
