Answer 1

You can export the certificate of your new app signature from .jks file in two way:

• Via CMD/PowerShell or Terminal : keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jks

• using Key Store Explorer software (download from here : http://keystore-explorer.org/downloads.html) and to know how to export in .pem format using this software see this 1:09 minute video in the following link : https://www.youtube.com/watch?v=2VsYakH3OUE
