Hello Clint Thanks for your answer to my question about this encrypted file. Your suggestion to directly encrypt the entries seems to be a good idea. You asked me what kind of encryption scheme I am planning to use. I have no idea at the moment. Because I don't want to spend a lot of time I am interested in "ready to use solution". That's why I am looking for a simple encryption function or something like that. It doesn't have to be a extremly secure one. Did you heard about such a function? Any ideas?? Let me know! If I find a solution, I'll let you know. Andy. Clint Brewer wrote: > Andy Hofmann wrote: > > > > hi all > > i have to make an applet which allows users to add some entries in an > > TextDataFile.
