A wretched little JS app viewable here that uses window prompts to collect parameters that will ultimately be used to generate a password. To use, load the page and click the big red button.
Part of my goal here was to start getting comfortable with user input in JS. If I were actually building a generator for myself, the UX would be quite different.
Please note: this generator makes extensive use of Math.random() and as such, DOES NOT YIELD A TRULY RANDOM PASSWORD. Do I think it's probably good enough? Well, yeah. But I don't want to make guarantees.
// most of the user prompts look something like this.
function collectLength() { // prompts the user to enter a length, then checks to see if it's valid, returns the input if so, re-prompts if not
var passwordLength = prompt("How long should your password be? Please type a number between 8 and 128:");
console.log("length is " + passwordLength);
if ((passwordLength > 7) && (passwordLength < 129)) {
pwLength = passwordLength;
collectLowerPref();
} else if (passwordLength != null) {
alert("Password must be at least 8 characters and no more than 128 characters. Please try again!");
collectLength();
}
else {
console.log("argh");
}
}pwgen.mov
I'd like to thank @StarryBlue7 for talking through the randomness algorithm with me.
