<h3 data-translate>Private Keys</h3>
<p>
<span data-translate-html>
Use private keys at
<a href="https://web.archive.org/web/20150707020924/https://brainwallet.org/" target="_blank">brainwallet.org</a>.
</span>
<span data-translate>Be careful - it can be easy to make mistakes if you don't know what you're doing.</span>
</p>
<h3 id="entropy-notes" data-translate>Entropy</h3>
<p>
<span data-translate-html>
Entropy values must be sourced from a
<a href="https://en.wikipedia.org/wiki/Random_number_generation" target="_blank">strong source of randomness</a>.
</span>
<span data-translate>This means flipping a fair coin, rolling a fair dice, noise measurements etc.</span>
<span data-translate-html>
Do <strong>NOT</strong> use phrases from books, lyrics from songs, your birthday or steet address,
keyboard mashing, or anything you <i>think</i> is random, because chances are overwhelming it isn't
random enough for the needs of this tool.
</span>
</p>
<p>
<strong><span data-translate>Do not store entropy.</span></strong>
</p>
<p>
<span data-translate>Storing entropy (such as keeping a deck of cards in a specific shuffled order) is unreliable compared to storing a mnemonic.</span>
<span data-translate>Instead of storing entropy, store the mnemonic generated from the entropy.</span>
<span data-translate-html><a href="https://en.wikipedia.org/wiki/Steganography#Physical" target="_blank">Steganography</a> may be beneficial when storing the mnemonic.</span>
</p>
<p>
<span data-translate-html>
The random mnemonic generator on this page uses a
<a href="https://developer.mozilla.org/en-US/docs/Web/API/RandomSource/getRandomValues" target="_blank">cryptographically secure random number generator</a>.
</span>
<span data-translate>The built in random generator can generally be trusted more than your own intuition about randomness.</span>
<span data-translate>If cryptographic randomness isn't available in your browser, this page will show a warning and the generate button will not work.</span>
<span data-translate>In that case you might choose to use your own source of entropy.</span>
</p>
<p>
<a href="https://bitcointalk.org/index.php?topic=311000.msg3345309#msg3345309" target="_blank" data-translate>You are not a good source of entropy.</a>
