I would like to encrypt a textual (configuration) file stored on disk.
Trying to use DES encryption I've had fatal error on client machines, I later found out the algorithm could not handle accented characters (!)
I suspect that was because I was using old packages (sun.misc.BASE64Decoder) - but I'm not sure that is the reason.
However, I'm looking for a simpler solution - I need a really simple encryption (I know some people would not agree on that) - not RSA of 128 bit keys or so, just obscuring the text from curious eyes.
It is really weird that I could not find a simple trivial solution on the web.
How can I implement a simple encryption scheme?
