The idea entered popular culture with the famous <a href=\"https:\/\/www.xkcd.com\/936\/\">XKCD correct horse battery staple<\/a> cartoon but is really much older. One of the first systematic ways of choosing the words is <a href=\"http:\/\/world.std.com\/~reinhold\/diceware.html\">Diceware<\/a>, a method that uses a die and a list of 1776 words. Each word takes 5 rolls of the die (or a single roll of 5 dice) but even a 5 or 6 word password can be chosen reasonably quickly. <\/p>\n<p> I&rsquo;ve written about Diceware <a href=\"http:\/\/irreal.org\/blog\/?s=diceware\">many times<\/a> in the past and have even provided two computer implementations, one in <a href=\"http:\/\/irreal.org\/blog\/?p=213\">C<\/a> and another in <a href=\"http:\/\/irreal.org\/blog\/?p=938\">Lisp<\/a>. Both use cryptographically secure random number generation and should be at least as secure as rolling a die. <\/p>\n<p> Over at <a href=\"https:\/\/www.youtube.com\/user\/Computerphile\">&lt;Computerphile&gt;<\/a>, Mike Pound has a video that <a href=\"https:\/\/www.youtube.com\/watch?v=Pe_3cFuSw1E\">explains and demonstrates Diceware<\/a>. He shows how a password is picked and explains why the result is secure. That security remains intact even if an attacker knows you are using a Diceware-like scheme and has a list of the candidate words. <\/p>\n<p> The video is just short of 11 minutes so you&rsquo;ll probably have to schedule some time or fit it into a coffee break. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The idea of choosing a list of common words as a password is fairly common and can lead to very secure passwords if the selection process is done randomly.
