title: Keystore: delete password
body: <p>I have a keystore (keytool key storage), which is used for signing .apk's from Eclipse-ADT.
  Due to the extremely annoying password requests at each export, I'm trying to figure out how to avoid reentering password.</p>
  
  <p>My current options are:</p>
  
  <ul>
  <li>by using Perl/X1::::XTEST, automate password entering (insecure)</li>
  <li>hack Eclipse to cache passwords (potentially insecure, explicit timeloss)</li>
  <li>remove keystore password, which seems to be the best possible idea</li>
  </ul>
  
  <p>Attempt to set empty password failed:</p>
  
  <pre><code>&gt;&gt; keytool -keystore /work/X/googleplay.key -alias X -keypasswd
  Enter keystore password:  
  New key password for &lt;X&gt;: 
  Password is too short - must be at least 6 characters
  New key password for &lt;X&gt;: 
  Password is too short - must be at least 6 characters
  New key password for &lt;X&gt;: 
  Password is too short - must be at least 6 characters
  keytool error: java.lang.Exception: Too many failures - try later
  </code></pre>
