# Security Model
|
||
|
|
|
||
|
|
## Basic goals
|
||
|
|
|
||
|
|
* Intents without permissions should only work based on user interaction (e.g. click a button in a dialog)
|
||
|
|
|
||
|
|
Android primitives to exchange data: Intent, Intent with return values, Send (also an Intent), Content Provider, AIDL
|
||
|
|
|
||
|
|
## Possible Permissions
|
||
|
|
|
||
|
|
* ACCESS_API: Encrypt/Sign/Decrypt/Create keys without user interaction (intents, remote service), Read key information (not the actual keys)(content provider)
|
||
|
|
* ACCESS_KEYS: get and import actual public and secret keys (remote service)
|
||
|
|
|
||
|
|
|
||
|
|
## Without Permissions
|
||
|
|
|
||
|
|
### Intents
|
||
|
|
All Intents start with org.sufficientlysecure.keychain.action.
|
||
|
|
|
||
|
|
* android.intent.action.VIEW connected to .gpg and .asc files: Import Key and Decrypt
|
||
|
|
* android.intent.action.SEND connected to all mime types (text/plain and every binary data like files and images): Encrypt and Decrypt
|
||
|
|
* IMPORT
|
||
|
|
* IMPORT_FROM_FILE
|
||
|
|
* IMPORT_FROM_QR_CODE
|
||
|
|
* IMPORT_FROM_NFC
|
||
|
|
* SHARE_KEYRING
|
||
|
|
* SHARE_KEYRING_WITH_QR_CODE
|
||
|
|
* SHARE_KEYRING_WITH_NFC
|
||
|
|
* EDIT_KEYRING
|
||
|
|
* SELECT_PUBLIC_KEYRINGS
|
||
|
|
* SELECT_SECRET_KEYRING
|
||
|
|
* ENCRYPT
|
||
|
|
* ENCRYPT_FILE
|
||
|
|
* DECRYPT
|
||
|
|
* DECRYPT_FILE
|
||
|
|
|
||
|
|
## With permission ACCESS_API
|
||
|
|
|
||
|
|
### Intents
|
||
|
|
|
||
|
|
* CREATE_KEYRING
|
||
|
|
* ENCRYPT_AND_RETURN
|
||
|
|
* ENCRYPT_STREAM_AND_RETURN
|
||
|
|
* GENERATE_SIGNATURE_AND_RETURN
|
||
|
|
* DECRYPT_AND_RETURN
|
||
|
|
* DECRYPT_STREAM_AND_RETURN
|
||
|
|
|
||
|
|
### Broadcast Receiver
|
||
|
|
On change of database the following broadcast is send.
|
||
|
|
* DATABASE_CHANGE
|
||
|
|
|
||
|
|
### Content Provider
|
||
|
|
|
||
|
|
* The whole content provider requires a permission (only read)
|
||
|
|
* Don't give out blobs (keys can be accessed by ACCESS_KEYS via remote service)
|
||
|
|
* Make an internal and external content provider (or pathes with <path-permission>)
|
||
|
|
* Look at android:grantUriPermissions especially for ApgServiceBlobProvider
|
||
|
|
* Only give out android:readPermission
|
||
|
|
|
||
|
|
### ApgApiService (Remote Service)
|
||
|
|
AIDL service
|
||
|
|
|
||
|
|
## With permission ACCESS_KEYS
|
||
|
|
|
||
|
|
### ApgKeyService (Remote Service)
|
||
|
|
AIDL service to access actual private keyring objects
|
