Azure AD B2C Signature Hash with Google Managed app Signing

Question

Is anybody using Azure AD B2C and Google Play who has selected the "Let Google manage and protect your app signing (recommended)" option?

I don't know how to follow the Azure portal directions on "Generating a production Signature Hash" in this circumstance. The instructions are to run this command:

keytool -exportcert -alias SIGNATURE_ALIAS -keystore PATH_TO_KEYSTORE | openssl sha1 -binary | openssl base64

I don't have a SIGNATURE_ALIAS or PATH_TO_KEYSTORE in this case.

Here is the solution, which I found here.

Go to the app in the Google Play Console and in the Release section of the menu options you will see:

The main screen will show:

Download the certificate and run this in the directory of the downloaded certificate:

openssl x509 -inform der -in deployment_cert.der -outform der | openssl sha1 -binary | openssl base64
