How do I protect the data in my Apps from hexeditors?

[georgep]

Qt is new to me so I have been playing with the examples.
I installed the mysql plugin and have played with the cachedtable example.
It uses the connection.h file from the examples/sql/ directory to connect to a mysql database.
The problem is that the variables(username, password,host) are viewable if I open the resulting .exe with WinHex program.

Tell me something I dont know pls. Thanks!

Hi, you could store an encrypted version of the password, and recalculate the original password at the moment you send it to the database. But you would have to store a key for that, which could be read with a hex editor and used to decrypt the password...

I think the only "safe" way would be to ask the user for username/password because no information would be stored in the executable.
