title: How to convert .pfx file to keystore with private key?
body: <p>I need to sign Android application (<code>.apk</code>).<br>
  I have <code>.pfx</code> file. I converted it to <code>.cer</code> file via Internet Explorer and then converted <code>.cer</code> to <code>.keystore</code> using keytool. Then I've tried to sign <code>.apk</code> with jarsigner but it says that .keystore doesn't content a private key.</p>
  
  <p>What I'm doing wrong?</p>
