Secure key storage

To store secrets (such as user authorization tokens, etc.), the OneEntry Native SDK uses the system's built-in secure storage: Keychain on Apple platforms and EncryptedSharedPreferences on Android.

However, in rare cases, you might need to override the default secret storage behavior.

Kotlin Multiplatform

OneEntryApp.initialize(
    host = "sample.oneentry.cloud",
    token = "vfrueaBVFuivUpv...hceupGVUGEWuvga"
) {
    keystore = object : Keystore {
        val map = mutableMapOf<String, String>()

        override fun get(key: String): String? = map[key]

        override fun set(key: String, value: String?) {
            if (value != null)
                map[key] = value
            else
                map.remove(key)
        }
    }
}

Swift

final class InMemoryKeystore: Keystore {
    var dictionary: [String : String] = [:]

    func get(key: String) -> String? {
        dictionary[key]
    }

    func set(key: String, value: String?) {
        dictionary[key] = value
    }
}

OneEntryApp.shared.initialize(
    host: "sample.oneentry.cloud",
    token: "vfrueaBVFuivUpv...hceupGVUGEWuvga"
) {
    CustomKeystore(InMemoryKeystore())
}
