add comment  1 Answer  Keep in mind that any method of
encryption that you use will need storing the key to decrypt the
encrypted data. This key will have to be available to your
application and thus to anyone who has access to your
application. By encrypting the data you change the problem of
hiding your data to the problem of hiding your key and there is
pretty much no way around it. The most you can do is to make
your data harder to read but it can't be made impossible to
read, unless you run your application on a trusted computing
platform, as I said in my answer to your previous question.
