• net.rim.device.api.system.RuntimeStore
2.
Create a hash ID for the object you want to store in the runtime store.
long MY_DATA_ID = 0x33abf322367f9018L;
Hashtable myHashtable = new Hashtable();
3.
Store the object in the runtime store and protect the object with the CodeSigningKey object. Only applications signed
with the key can read or change the object.
RuntimeStore.put( MY_DATA_ID, new ControlledAccess( myHashtable, key ) );
4.
Make sure that the object is protected with a particular code signing key, invoke RuntimeStore.get, providing as
parameters the hash ID for the object and the CodeSigningKey object.
Protect persistent data using code signing keys
1.
Import the following classes:
• java.util.Hashtable
• net.rim.device.api.system.PersistentObject
2.
Create a hash ID for the object you want to store in a persistent object.
long MY_DATA_ID = 0x33abf322367f9018L;
Hashtable myHashtable = new Hashtable();
3.
Store the object in the persistent object and protect the object with the CodeSigningKey object. For example, after
a BlackBerry device application runs the following line of code, only code files that are signed with the RSAE .key file can
read or overwrite the object in the persistent object.
persistentObject.setContents( new ControlledAccess( myHashtable, key ) );
4.
Make sure that the object is protected, invoke getContents using the CodeSigningKey object as a parameter.
Hashtable myHashtable = (Hashtable) persistentObject.getContents( key );
