Hi,

You still have not clarified whether anyone should be able to access the data outside of your application. Also are there concerns that one company using your application may then be able to access the data of another company ?

If a user is to be allowed access to the data why not provide them with the password ? This logic applies to any authentication system - it's like saying the company owner should go round and logon all the secretaries to Windows in the morning . Or do you mean you want your application to automatically recover the encryption key on startup ?

I think you're maybe trying to use Cryptor to enforce security in a way for which it is not intended. Cryptor is great for restricting access to data to specific applications. But if you need more fine-grained control then the application itself should take responsiblility for any additional authentication.

Best solution is probably an 'Import' option in your application (or a small standalone). If the folder containing the existing encrypted data is registered then registering the new files with the 'masterkey' and copying them to the main folder should do the trick.
