title: How to change PKCS12 keystore file from RSA1024 to RSA2048 and be able to update the app in Play Store?
body: <p>More than 3 years ago we have started with our app on Play Store and we were using RSA1024 keystore .p12 file. However, since JDK 1.8_121 1024 bit keystore files are not supported by Oracle, so I cannot use newer java version to compile the app.</p>
  
  <p>When I tried to create RSA2048 bit key file, it works, however I couldn't upload the update cause a "wrong developer information" or similar.</p>
  
  <p>Any idea how to create 2048 bit key from 1024 bit key and to be recognized by Google Play Store?</p>
