WinRAR Password Cracker

Inspiration

As a student of cybersecurity for two years, I had already made rainbow tables, so this was the next logical step.

What it does

It can crack any encrypted file's password except those that contain characters MSDOS would mistake for commands. (i.e. <>/?:")(&^%!)

How I built it

I taught myself batch script over the course of two or three weeks reading others' examples and looking up syntax on the internet.

Challenges I ran into

The syntax of batch script is ancient and not designed for complex programming.

Accomplishments that I'm proud of

Despite my program never fully functioning before the competition, I wrote it from scratch at the competition and made it free of glitches.

What I learned

How to write in a new language.

What's next for WinRAR Password Cracker
