Now I need unit 3, 4 and 5 done. Can you help me?
Need unit 3 by tomorrow and unit 4 and 5  by Thursday next week September 9th

Windows stores passwords using the NT LAN Manager (NTLM) hash.  This hash is created by hashing the plain text password with the MD4 algorithm.  There is no salt used.  The lack of salt enables the use of a rainbow table to lookup passwords from their hash.   For this assignment you will create a rainbow table for a set of passwords. 

More about NTLM: http://techgenix.com/how-cracked-windows-password-part1/

For this assignment you will create a Rainbow table for NTLM passwords.   Use the following list of steps as a guide.

1. Use the sys library to read a command line argument that is the name of a password dictionary file.
   For your submission used the password dictionary file found at this link: http://www.openwall.com/passwords/wordlists/password-2011.lst (Links to an external site.)
2. Open the password dictionary. 
3. Loop through the contents of the password dictionary one password at a time.
   • Strip any leading and trailing whitespace characters.
   • encode the word as ‘utf_16_le’ (https://docs.python.org/3/library/stdtypes.html#str.encode (Links to an external site.))
   • Use the Python library hashlib to hash the password with the md4 algorithm.
     • import hashlib
     • hashlib.new() to select an algorithm
     • use update() to create the hash
     • use hexdigest() to refer to the hash
   • Store the password in a Python dictionary with the hash as the key. (https://docs.python.org/3/tutorial/datastructures.html#dictionaries (Links to an external site.))
4. Sort the list of keys from your dictionary
5. Use a for loop to print all keys and passwords. Print on hash and password pair per line. Structure each line as follows to allow a password to be looked up easily from it’s hash:
   [hash]:[password]
6. Store the output of your program as rainbow_table.txt. 
   *** Run your program as ‘python3 rainbowtable.py dictionary.txt > rainbow_table.txt’
7. Name your script rainbowtable.py

Try to answer the following question, 

why are evolutionary models considered by many to be the best approach to software development in a modern context?

 Please refer to Section 2.5.3 from the textbook

Activity 2

Activity I: A young engineer decides to save $240 per year toward retirement in 40 years.

1. If he invests this sum at the end of every year at 9%, then how much will be accumulated by retirement time?
2. If by astute investing the interest rate could be raised to 12%, then what sum could be saved?
3. If he deposits one fourth of this annual amount each quarter ($60 per quarter) in an interest bearing account earning a nominal annual interest rate of 12%, compounded quarterly, how much could be saved by retirement time?
4. In part (c), then what annual effective interest rate is being earned?

Activity II: Maurice Micklewhite has decided to replant his garden. Show him what the cost is of making an erroneous decision at various stages of the project, starting with conceptual design and ending with the ongoing maintenance of the garden.
