Whoa there! Your browser doesn't have the getRandomValues() function.
|
|
This means that dice rolls you make <em>will not be cryptogrpahically secure!</em><br/>
|
|
Please try another browser. Otherwise, proceed at your own risk.

<h3>About Diceware</h3>
|
|
|
|
Weak passwords are a big flaw in computer security due to a lack of "entropy"
|
|
or randomness. For example, how many times have you used the name of a pet or relative or street
|
|
in a password, or perhaps the number "1". Not very random, is it? :-)
|
|
Worse still, if
|
|
passwords are reused between services, <a href="http://www.businessinsider.com/biggest-password-mistake-2014-8"
|
|
>that increases your security risk</a>.
|
|
</p>
|
|
|
|
Fact is, humans are terrible at remembering random combiations of letters and
|
|
numbers, but we are great at remembering phrases of words. That's where Diceware comes in.
|
|
</p>
|
|
|
|
This Diceware web app is based on the proposal at <a href="http://world.std.com/~reinhold/diceware.html">http://world.std.com/~reinhold/diceware.html</a>
|
|
wherein virtual dice are roled 5 times, and the 5 digit number used against a lookup table of words.
|
|
4 dice rolls gives you 4 random words which are easy for a human being to remember, yet have
|
|
a high amount of entropy which makes them hard to crack.
|
|
</p>

<h3>FAQ: Why not use LastPass or a similar product?</h3>
|
|
|
|
By all means, feel free to do so. LastPass is an excellent product and I highly recommend it.
|
|
That said, there's no reason that Diceware cannot be used concurrently with LastPass. Personally,
|
|
I like passwords that I can remember.
|
|
|
|
|
|
<h3>FAQ: Are these dice rolls cryptographically secure?</h3>
|
|
|
|
Yes, insofar as we're using the getRandomValues() function in Javascript, and you trust that your
|
|
browser and computer have not been compromised or otherwise tampered with. Keep in mind that a not-so-theoretical attack
|
|
would be for an attacker to compromise the random number generator on your computer so that
|
|
anything that is encrypted (or passkeys generated) would be suspectible to less intense cryptoanalysis.
|
|
|
|
|
|
<h3>FAQ: Is the source available?</h3>
|
|
|
|
Yep! You can grab a copy at <a href="https://github.com/dmuth/diceware">https://github.com/dmuth/diceware</a>
|
|
</p>
|
|
|
|
In fact, if you are nervous about generating a password on a website (even though the password is actually
|
|
generated by Javascript in your browser), I would encourage you to download the source and run it locally.
