<p>Encodes the username/realm/password triplet for Digest
authentication. (That is, it returns a stringified MD5 hash of
<em class="parameter"><code>username</code></em>

the form that is needed as the return value of

<p>For security reasons, you should store the encoded hash, rather
than storing the cleartext password itself and calling this method
only when you need to verify it. This way, if your server is
compromised, the attackers will not gain access to cleartext
passwords which might also be usable at other sites. (Note also
that the encoded password returned by this method is identical to
the encoded password stored in an Apache .htdigest file.)</p>
