This is a short project designed to show people how safe their passwords (or password ideas) are through the metric of information entropy.
This is a hobby application meant for illustrative purposes and, as such, the entropy amounts may not be perfectly computed. A more reliable source (like the KeePassXC application) should be used as a double check for important tests.
DISCLAIMER : This application does not connect to the internet, and in no way shares any information entered. Still, you probably shouldn't put your real passwords in as a matter of general opsec.
Entropy is a measure of how hard a given password is to guess. "Guessing" here can refer to a range of methods from brute force to more intelligent approaches.
In other words, the higher the entropy, the more secure the password.
The Keepass Help Center website provides the following chart for the relationship between password entropy and "quality" :
| Bits | Strength |
|---|---|
| 0-64 | Very weak |
| 64-80 | Weak |
| 80-112 | Good |
| 112-128 | Strong |
| ≥ 128 | Very strong |
Simply enter your password, and click run to see your entropy with respect to some of the main password-cracking methods.
You can also answer some personal questions in the "Customize" tab to see how hackers can use specific knowledge against you.
