I noticed that Google has the Manage your app signing keys service, that it is possible to replace my key with the google key.
For this I must follow some steps that is:
Download the PEPK tool to export and encrypt your private key.
Use the command below to run the tool that will export and encrypt your private key. Be sure to replace the highlighted arguments in bold. Then enter the key and keystore passwords in the requests.
$ java -jar pepk.jar --keystore = foo.keystore --alias = foo --output = encrypted_private_key_path --encryptionkey = encrypted key
Upload your encrypted app signing private key.
Generate a new upload key. Follow these instructions to generate a new key.
Export the newly-generated upload key certificate to the PEM format. Be sure to replace the highlighted arguments in bold.
$ keytool -export -rfc -keystore upload-keystore.jks -alias upload -file upload_certificate.pem
Upload the certificate of your upload key to register with Google.
I just stopped at the second one because I do not have the .keystore file (at least, I think) I have the jks I created in the act of creating the signed apk.
The question:
Can the .jks file be this .keystore? Or do I have to generate this file?
