*** ** * ** ***
E2eeContactKeysManager provides access to the provider of end-to-end encryption contact keys. It manages two types of keys -[E2eeContactKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeContactKey)and[E2eeSelfKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeSelfKey).
- A[E2eeContactKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeContactKey)is a public key associated with a contact. It's used to end-to-end encrypt the communications between a user and the contact. This API allows operations on[E2eeContactKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeContactKey)s to insert/update, remove, change the verification state, and retrieving keys (either created by or visible to the caller app).
- A[E2eeSelfKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeSelfKey)is a key for this device, so the key represents the owner of the device. This API allows operations on[E2eeSelfKey](https://developer.android.com/reference/android/provider/E2eeContactKeysManager.E2eeSelfKey)s to insert/update, remove, and retrieving self keys (either created by or visible to the caller app).
Keys are uniquely identified by:
- ownerPackageName - package name of an app that the key belongs to.
- deviceId - an app-specified identifier for the device, defined by the app. Within that app, the deviceID should be unique among devices belonging to that user.
- accountId - the app-specified identifier for the account for which the contact key can be used. Using different account IDs allows for multiple key entries representing the same user. For most apps this would be a phone number.
Contact keys also use lookupKey which is an opaque value used to identify a contact in ContactsProvider.
