Encrypt Cached User Information

[eeatonaws]

When a user logs in using their phone number, CognitoIdentityProviderCache.xml file is created and stored in shared preferences and it holds the user's phone number in persistent storage. The format is as follows:
<string name="CognitoIdentityProvider.276dt8eeub4a9cmn9hlhs35u1d.{#phonenumber}.idToken.encrypted.keyvaluestoreversion">1</string>

Username is also used to form a key for the local cache. Although the data is stored in private mode, which will only allow apps that wrote the value to read it (unless root/mount the disk), we would like an option to encrypt the user information stored in shared preferences.

Can you provide some more information on what the use case is what you are trying to achieve. The user information in V2 is now already stored in encrypted shared preferences except for deviceMetadata which is still stored in sharedpreferences. For more information please visit the docs page. I am going to keep this ticket open as this is not yet fully resolved.
