Encrypt Sqlite with Qt using some open source solution

My application uses Qt 4.6 to access sqlite. Now I have a requirement for encrypting sqlite database. When searching, I find SEE , but it is licensed.

My problem: I want to encrypt sqlite database using QT or some open source solution that is compatible with Qt. Tell me some link or tutorial if you know.

Sqlcipher The SQLite extension is what you need. Take a look at QTCentre about creating a sqlite version that supports out-of-box encryption. The main advantage of this version is that it provides a standard qt interface through a user plugin. In addition, it is licensed by BSD.

Not sure if this is a good solution, but what about encrypting the file before opening the database and encrypting it again after closing it?

In any case, I don’t think there is a way to make the data 100% safe. There will always be a moment when the data is unencrypted (when your application reads it), and someone can get it at that time.
