How does Ionic/Cordova generate hash key?

It seems Cordova use ~/android/debug.keystore with the password android

To get it :

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

With password : android

One answer that worked for me is this one:

• Copy the apkname.apk file you want to know the hash of to the 'Java\jdk1.7.0_79\bin' folder
• Run this command keytool -list -printcert -jarfile apkname.apk
• Copy the SHA1 value and convert it using this site
• Use the converted Keyhash value (ex. zaHqo1xcaPv6CmvlWnJk3SaNRIQ=)
