Embedded Files
As part of our final project we had 4 different options, 3 involving code, so here is my implementation.
Dictionary Attack Using Different Hash Algorithms
Dictionary Attack Using Different Hash Algorithms
Overview: As part of this project, you will write a program that will measure password security by employing a variation of the dictionary attack. Given a file of a limited amount of words(100~200, no more than 500), allow the end user to pick up to any three words(due to limited computing power) from the word list to concatenate together in any order and form a random password. Write a program to crack that random password, and count how many attempts were made or/and how much time was consumed using a dictionary attack. Compare the efficiency of different hash algorithms. Plot a graph to visualize the difference.

The main method is the thing that will actually call the different Hash Test functions as well as get user input and latter on make the graphs. The main function is largely the same across all functions except for the call to the function replacing the HashFunction that is currently in the code.

The first approach was of course to do a simple for loop which ended up taking around ~3 minutes to do the hardest password in the 500 word dictionary of amongamongamong. In the profiler we see that it takes this long due solely to having lots of iterations with a total of 125,250,500 iterations of the loop.

Process Pool
Process Pool
Since the for loop took so long due to the number of iterations then the easiest way to fix that is to parallelize it leading to using a multiprocessor pool. This approach took around ~75 seconds to do the hardest password in the 500 word dictionary of amongamongamong. In the profiler we see that the bottle neck is using locks, which I suspect is due to the multiprocessor since my code doesn't use locks. However there is a even bigger issue which is no early termination meaning it will test every possible permutation instead of only testing a few.

When thinking of how to fix the early termination problems I was learning more about multiprocessor map functions. That is where I thought more about what I really wanted to do, originally I was just trying to emulate the for loop implementation and have it be the exact same. However I realized that by trying to match the for loop implementation exactly would hinder performance. That then lead me to using imap_unordered instead of map which had the benefit of first being unordered which improved performance since I didn't need things to be ordered. Second is that to my knowledge it returned values as quickly as they were processed which added early termination. This implementation also meant that count would be inconsistent since it all depended on how quickly each core could process data, this is when I also started to return the decoded password instead of just count and time to ensure that the password was correctly found. In terms of performance it is now ~55 seconds for the hardest password in the 500 word dictionary of amongamongamong and was the fastest version for a while and is what was used to estimate the time taken in the initial print. In terms of profiler it is still limited by locks.

Since the bottleneck for a Pool was locks then the idea was to not use a pool but instead make my own. However this ended up making my code very messy since I had to use a queue to store my data instead. Although the code could probably be improved, for example the sleep could be removed, however the current bottleneck is method 'dump' of '_pickle.Pickler' objects which a quick Google search cites Windows being unable to spawn many processes as the problem. In terms of performance it is ~100 seconds for the hardest password in the 500 word dictionary of amongamongamong.

Since the bottleneck seemed to be Processes then what if I didn't use Processes but instead Threads. Thus after many iterations I am left with the following code. Although it may not be perfect the longest total time is in the hashing function meaning that my code is taking the longest rather then something else which has happened. For example sleep originally took the longest, that got fixed then _winapi.WaitForMultipleObjects took the longest and when that was fixed it was threading.is_alive. However now it is simply how long it takes to test all permutations. In terms of performance it is ~190 seconds for the hardest password in the 500 word dictionary of amongamongamong.

Since having several processors and managing them myself seemed the most promising then I went back to that idea. However this time I opted to test pickle's dump on my own which gave me the insight that the thing that was slow was lists. Thus I removed the list and instead passed a itertools.product iterator for the previous permutations and a subsection of the words list. Now in the running function I append each word to the previous permutations to be able to test all permutations. This combined with other smaller optimizations made it so that I finally have a new fastest time of ~30 seconds for the hardest password in the 500 word dictionary of amongamongamong. In terms of profiler everything is roughly the same with no big times, thus the next optimization is probably having a better way of testing if every processor is done since that is around 5 seconds of time.

Several Processors Version 2 with Events
Since the goal was to remove filtering a bunch then the idea was to have the code wait until a signal that a process ended. Said signal came in the form of a multi processor event which was sent by a process on completion. In terms of performance it takes ~25 seconds for the hardest password in the 500 word dictionary of amongamongamong. However there were some issues, mainly in that the signal was sent slightly before the process properly finished causing me to have a timeout on the wait to prevent the program from halting. This meant that the filter was still running more then it has too as evident by the ~2500 calls to it rather then the theoretical 48.

Several Processors Version 2 with Pipes
To solve the previous issues I switched from events to pipes which unlike the events, at least to my knowledge, have a buffer so they can store how much data was sent. This solved the issue of what if 2 processors send a event before the event was cleared. I also realized that due to terminating processes my count was wrong in that it wasn't a accurate representation of how many comparisons I did. This is due to me only adding my count at the end of the process. Which of course only happens when the process finishes, which terminate doesn't do. Thus I resolved this issue by using events and threads to signal when a process should end and then only join them rather then terminate them, this also removed the need to filter processes which further improved performance. Â In terms of performance it takes ~22 seconds for the hardest password in the 500 word dictionary of amongamongamong. Through the cProfiler we see that the most time is spent on waiting indicating that we should now look at the processor code to see if it can be optimized.

Several Processors with Pipes Version 2
Several Processors with Pipes Version 2
The first step in optimizing the processor code was to run a cProfile on the code, that then highlighted many bottlenecks that I could solve. The main bottlenecks unsurprisingly involved hashing, in that new, update and digest where the main times but also encoding and join. For the hashing bottleneck I brought new out of the inner loop and instead used update and copy to update a hash object instead of creating a new one. For the encoding I opted to encode words in main as that let me encode all permutations before hand. For join there was nothing specific but it did decrease most likely due to using bytes instead of strings. In terms of performance there was a drastic decrease with it taking ~14 seconds for the hardest password in the 500 word dictionary of amongamongamong. Without some major changes I doubt the processing code will be any faster.

With the deadline quickly approaching I ended my optimization journey with one last optimization. As part of this assignment we were allowed to use the length of the inputted password to quickly decrypt it. I believe we were allowed to do this since the intended solution was to iterate through every possible combination and this would significantly speed up the process. An example of this is in the first attempt were after using the length with the soon to be mentioned optimizations turned the ~3 minute run time to around ~11 seconds. Said other optimizations were also sorting the word list by length before trying to decrypt it as this let me possible removed all permutations and even skip over processes. The last change was also adding the graphing portion of the assignment. In terms of performance the length filter makes it extremely difficult to know which word combination takes the longest however I have not seen any take more then 10 seconds and the longest was ~8 seconds which was easteasteast.
