Java encryption alternitive to hardcoded key

Question

I am new to encryption.

I have looked at the javax.crypto documentation and got encryption of a file to work using this code ...

File saveFile = new File         


        

Answer 1

the most secure method is not use any encryption, just put your user.properties to your home directory, with following code:

String userhome = System.getProperty("user.home");
String username = system.getProperty("user.name");
String hostname = java.net.InetAddress.getLocalHost().getHostName();

if (hostname.equals("webserver") && username.equals("root")){
ResourceBundle user = ResourceBundle.getBundle(userhome/ "user.properties");
}
