title: Store database password in program with no key in source code
body: <p>I am writing a simple database application. The program should get database information (host,name,user,pass) and store them for next uses. So I need to encrypt them and store encrypted information in a file. On the other hand I don't want to put any passwords in program code. My question is how should I store key for encryption algorithm in program? (the key used for encrypt database information)</p>
