DICEWARE WORD LIST PDF

Roll some dice to get a bunch of five-digit numbers, then look up each number in a word list. These words form a secure, memorable, random passphrase — without using or trusting any software. Sure, you could just download the word list and scroll around on your computer screen, or print it out on your inkjet. Easier to use, store and carry than a loose sheet of papers from your printer. It fits nicely in your hand and is easy to flip through.

Frequently Asked Questions How do I use it? Click on one of the numbered passphrase generator buttons above. Click again to generate a totally new passphrase. For extra security you can manually roll physical dice two or five die rolls for each symbol or word respectively and enter the results to add a word to your passphrase.

Each word or symbol displayed is shown with the index number that was used to look it up in the diceware word list. You can copy the generated passphrase from the copyable string on the page. You should store it somewhere safe and secure. You might want to write it down and refer to the written version until you can remember it. What inspired you to create this? I have been using Diceware for several years but its kind of a hassle for everyday passphrases.

I wanted something that was easy to use, and yet secure for all but the most extreme security needs. Is it safe? It depends. Are you the target of a nation-state level adversary? If so, you should probably not use this and should instead use Diceware to roll real physical dice and look up the words from the wordlist manually. This is the official recommendation of the Diceware FAQ. As a normal person, even if you have high security needs like protecting long term cryptographic keys, you should be safe using this tool.

Using real dice is the most secure way, but relying on the random number generator should be safe as well. Does this use a cryptographically strong random number generator to choose the words?

The JavaScript window. You can learn more about window. Many cryptographic library authors are now targeting the browser environment and most are using this API as their primary source of entropy so you are in good company. What URL should I be using to access this application? Does this application send any data anywhere? No security sensitive information such as your selected passphrase size, die rolls, or the generated passphrase ever leaves your browser or is logged anywhere. Once the initial page is loaded as static files everything is done locally in your browser.

In fact, once you load this application in your browser you can turn off your network connection and it should work just fine. Of course these guarantess only apply if you are viewing this page from a rempe.

Where is the code for this application being served from? There is no server side component and no database. All of the JavaScript and other assets are versioned in the repository and no code is served from outside of the repository. How should I use this most safely? You should ensure that: You read about Diceware and understand the strengths and limitations of this approach. No public machines! You close the browser window, when you are done. This is enforced with HSTS.

You are using the latest version of a modern browser. What is entropy? Entropy is a measure of the uncertainty or randomness of a system. The concept is a difficult one to grasp fully and is confusing, even to experts. Strictly speaking, any given passphrase has an entropy of zero because it is already chosen. It is the method you use to randomly select your passphrase that has entropy. Entropy tells how hard it will be to guess the passphrase itself even if an attacker knows the method you used to select your passphrase.

A passphrase is more secure if it is selected using a method that has more entropy. Entropy is measured in bits. The outcome of a single coin toss -- "heads or tails" -- has one bit of entropy. Arnold G. The total is the sum of the entropy in each full word or special character. Is the source code available and can I run my own copy locally?

The source code is available on Github. Its a simple static HTML application and you can clone and run it by opening the index. When run locally it should work when your computer is completely offline. The latest commits in the git repository are signed with my public code signing key. Would XKCD approve?

Deep Dive: EFF's New Wordlists for Random Passphrases

This embed will serve content from archive. For most applications, we suggest making a six-word passphrase. Step 1: Roll five dice all at once. Note the faces that come up without looking at the wordlist yet. On our dice, the EFF logo is equivalent to rolling a one. Step 2: Your results might look like this reading left to right: 4, 3, 4, 6, 3. Write those numbers down.
