How to correctly collect database login info?

So connecting to the database requires host, username, and password. How can i collect them so none of the third parties can view it except native java? (others can access the config file)

 

Ok. (What issues? Like storing the key?) Well then, how should i store the data without being accessible by server administrators?

 

Because some server owners may not want other administrators to know the database host, user and password.
Also, flat file is accessible because it stores characters. Just there isnt a default program to open it.

 

Where does java.util.prefs store the preferences?

 

Ok i finally found the answer. The preferences are registered in HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs and HKEY_CURRENT_USER\Software\JavaSoft\Prefs. For Windows, they are Windows Registry. I think this is the safest way to store the host, user and password. But this does not solve about how to collect data safely.

 

So thats why there is a BackingStoreException. Thank you. I will make edits.
Yes, it works on linux.

 

Just my two cents but perhaps if you don't want your server administrators accessing the database then there is a problem much larger than keeping your credentials secure? The entire point of server administrators AFAIK is to administrate the server, and they can't administrate the server effectively if they don't have access to parts of it.

tl;dr; if you don't trust your server admin they shouldn't be a server admin probably.

Anyway, that's just my opinion.
