How Secure is Your Password is a rudimentary method of testing how long a desktop PC at 4 billion calculations/second would take to crack the password. It is not too accurate, but it was fun to make! The program will adjust if you insert numbers or symbols, and, of course, the longer it is, the longer it will take to crack.
I got my idea from https://howsecureismypassword.net. You can use this to test passwords generated with my password generator below. https://scratch.mit.edu/projects/70956172/
