title: Signing apk with .p12
body: <p>I am going to update my client's app which is available on Google PlayStore.
  And I have only a <strong>.p12</strong> file with password, not <strong>.keystore</strong> file.</p>
  
  <p>I am wondering if it's possible to publish the updated version to Google PlayStore.</p>
  
  <p>Sorry for basic question. I am so confused with that. Thank you in advance for your assistance.</p>
