Java - Storing data in a file

NGRU-Kamikazie

Hey,

How do I store data from a program into a file so it can be re read at the program initiation? The file cant be read by anyone as it would contain passwords in it. I know how to export using EasyWriter to a file, but it comes out as a .txt and can be opened in any text editor, is there a different format to which can onlybe read by the program or a way to actually store it in the .class file it self?

Sounds like you want to encrypt output files: try this on

You can do alot with serialisation. The object will be serialized into unreadable text. You can still view the text on the other hand but not many people will be able to make something out of it... I'm actually starting to doubt if this is what you want?

Also you may try to store the hashes of the passwords as normal text. If it's good enough for operating systems...
