Why cant i find a good way to save?

I am writing a software program that requies a password to enter because the data within is confidential. I need a way of saving the data added to the program in a way that is NOT readable without the program. Now here is the awkward part. Using the registry is a bad idea cos it can be cracked easy, INI files are a prob for the same reason and if i use a database file then it ends up missing when i createthe software and use on another computer, i cant find the database???

So to tie this up, what way should i use to save the data from my program??
If you say encryption then explain how please. Any other method will be good as well

Are you adding the db to your installation package? How is your connection string setup? Hardcoded or relative?

dont know, what do you mean?

you can find many encryption and decryption methods in code bank search for it and get back to us if you need more help.

What program are you using to package your program, create the setup installer.

What do you mean by "cant find the database"?
