![]() The whole point of using padded passwords is to adopt a much more you-friendly approach to password design. The calculator then puts the resulting large numbers (with lots of digits or large powers of ten) into a real world context of the time that would be required (assuming differing search speeds) to exhaustively search every password up through that length, assuming the use of the chosen alphabet.Īnswering that question is the reason this page exists. This calculator is designed to help users understand how many passwords can be created from different combinations of character sets (lowercase only, mixed case, with or without digits and special characters, etc.) and password lengths. So what IS the “Search Space Calculator” ? And no password cracker would wait 17.33 centuries before checking to see whether “Password” is the magic phrase. Yet the Search Space Calculator above shows the time to search for those two passwords online (assuming a very fast online rate of 1,000 guesses per second) as 18.52 minutes and 17.33 centuries respectively! If “123456” is the first password that's guessed, that wouldn't take 18.52 minutes. The #1 most commonly used password is “123456”, and the 4th most common is “Password.” So any password attacker and cracker would try those two passwords immediately. Since it could be easily confused for one, it is very important for you to understand what it is, and what it isn't: IMPORTANT!!! What this calculator is NOT. Simplicity and power of the “ Password Haystacks” concept. The prestigious “ Consumer Reports” has also picked up on the (The Haystack Calculator has been viewed 8,487,836 times since its publication.) Limited to, at most, a few hundred guesses per second.

With JavaScript, everything stays in your browser where it belongs and is never sent anywhere for any purpose. If your test passwords were sent back to GRC for server-side analysis, it would not only be much slower and more cumbersome, but also inherently open to privacy questioning. While we have bent over backwards to make GRC's many other site features completely functional without any client-side JavaScript (mostly to thumb our nose at the rest of the world to show that it can be done) the highly interactive nature of this page really screams out for a JavaScript solution.īut also, performing this page's calculations with client-side JavaScript is the only way to provide you with privacy. (Because we DON'T have JavaScript)If you are reading this, your browser's built-in JavaScript interpreter is disabled and is thus (not surprisingly) unable to interpret JavaScript.
