Hi guys! Has anyone performed database encryption with SQLDelight? Are there any links with good documentation?

Example of sqldelight with sqlcipher. This really needs a blog post to explain, but the code config is here: https://github.com/touchlab-lab/KaMPKit-encrypted/blob/main/shared/src/iosMain/kotlin/co/touchlab/kampkit/KoinIOS.kt#L38

SQLCipher is added in the gradle config, although you can also do that directly in xcode. Here’s the gradle version:

cocoapods {
        summary = "Common library for the KaMP starter kit"
        homepage = "<https://github.com/touchlab/KaMPKit>"
        framework {
            isStatic = false // SwiftUI preview requires dynamic framework
        }
        ios.deploymentTarget = "12.4"
        podfile = project.file("../ios/Podfile")
        pod("SQLCipher") {
            version = "~> 4.5"
        }
    }

Focus on the pod("SQLCipher") section…

Finally, you need to get your secret encryption key in there somehow. That’s true of any encrypted database. We have it right in the code, which is definitely not how you should do that. https://github.com/touchlab-lab/KaMPKit-encrypted/blob/main/shared/src/iosMain/kotlin/co/touchlab/kampkit/KoinIOS.kt#L39

I've had it working in Android for a few years now and it works great (sorry I don't have code to share at the moment).

The only real issue I've seen with it is that some users, some of the time, crash because the .so isn't found. I don't think this is specific to SqlCipher or SqlDelight though
