The SHA-256 Key is a string used to identify one or more apps.
You can find the SHA-256 Key by using your .keystroke or .jks release key with the following command:
keytool -list -v -keystore [my-release-key.keystore]
- In order to support Android App Links, a SHA-256 Key will need to be included in your Bitly Android app. It is used to create the Digital Asset Links JSON file on the Custom Domain that will support Android App Links.
