Exporting for Android using APK Expansion
I am trying to upload my game to Google Play and I would like to use the APK expansion option for exporting. In the APK Expansion export section there are three fields: Enable, Salt, and Public Key.
So I have two main questions:
My understanding is that Salt has something to do with cryptography but I'm not 100% sure what it does or what it should be. Would any word/phrase work? Should I treat this like a password?
What needs to go into the Public Key field? I managed to create a Keystore and a public certificate using Keytool, but this field requires text and I could not find any documentation on it. My working theory is that I need to use the
keytool -printcert -rfc -file PublicCertificate.crtcommand and use that output (which looks like multiple lines of random letters, numbers, and symbols). Is that correct?
