# 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
