How does Ionic/Cordova generate hash key?

Question

I'm working on adding Facebook API integration with ionic/Cordova and am trying to find the debug hash key that is generated for my app when I do:

ionic build android

I know that it generates a new .keystore file at /userhomedir/.android/debug.keystore. But what does it set as the alias and password? And how can I retrieve this hash key after Cordova has created it for my app. I don't see the hash key being printed anywhere during the build process.

I need the generated hash key to give to Facebook API to use their sign on SDK

Answer 1

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

Answer 2

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=)

Answer 3

keytool -genkey -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-alias
