The Python Password Generator compiled into a lovely executable file for your generative needs. I find it fun to put ridiculously long lengths, resulting in half an hour processing times that really don't make your computer happy.

PS: Generate a length of 74088185856 for 69GB files. This will probably kill the process or take literal days to process.
If you do want to do this, I'd recommend using my much more efficient program in my https://github.com/JustAHubber/Scripts repository.
