Password Generator

This was a small project of mine from 2022, which I used to learn some basic Windows Form GUI programming in C#. Cybersecurity is hugely important to me, so I combined these two aspects into this simple Password Generator. Another function of the project was to explore and research Cybersecurity, which I found useful as I now have a deeper understanding of what makes a good password, and how to best keep your online accounts secure.

The application itself is quite primitive. There is support for customising the types of characters that are included in the generated password(s) – lower/upper case, numbers & symbols, as well as the length of the password. The number of passwords to generate can also be specified. The random numbers are sourced by the C# RNGCryptoServiceProvider API, which produces better randomness than the usual System.Random option.

I emphasize the adjustability of the passwords because there are many websites that seem to place restrictions on what your password can and can't look like. I have encountered websites that limit to a maximum of 20 characters with no symbols, which I suspect is because of storage concerns for the database (although I think this is questionable from a security standpoint).

Of course, the passwords are useless without a password manager – nobody will remember a random string of 128 characters by heart. In this regard the application is lacking, as I was satisfied with my progress by the time I stopped its development. Anybody serious about their Cybersecurity should use a community-developed, self-hosted password manager, and for this I recommend KeePassXC.

Another feature is that it can be run through the command line instead of as a GUI application. Using arguments passed to the .exe, it's possible to configure all the aforementioned settings for generated passwords.
