I pull a key and credentials from a database service that gets encrypted through HTTPS. I then use that key to encrypt data in a local sqllite database. I made it so I have to pull the key from the service everytime I want the encrypted data from my local Sqllite. Just don't ever lose the key ;)
Don't know how secure this is, but it was the approach I took. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
