So in lieu of no official database encryption support from objectBox, we've gone the route of field encryption using the property converters.

We've implemented AES-256 encryption on String fields.

Thus far performance tests show the following:

  • No encryption, 1000 objects (13 fields / object) write ~ 2740ms
  • Encrypted, 1000 objects (13 fields, 6 encrypted) write ~ 6434ms
  • No encryption, 1000 objects (13 fields / object) read ~ 58ms
  • Encrypted, 1000 objects (13 fields, 6 encrypted) write ~ 70ms

Checkout this handy AES lib: https://github.com/scottyab/AESCrypt-Android

An example of the property converter class

class EncryptionConverter : PropertyConverter<String, String> {

    override fun convertToDatabaseValue(entityProperty: String): String {
        return AESUtil.encrypt("YOUR_SUPER_SECURE_KEY" , entityProperty)
    }

    override fun convertToEntityProperty(databaseValue: String?): String {
        return AESUtil.decrypt("YOUR_SUPER_SECURE_KEY" , databaseValue)
    }
}

Your field in entity class would look something like this

@Convert(converter = EncryptionConverter::class, dbType = String::class)
    var username : String = ""

Also remember, with field encryption you're giving up partial field lookup capability

There is no built-in support for encryption.

There is a feature request to support it. We welcome your suggestions. https://github.com/objectbox/objectbox-java/issues/8

ObjectBox currently depends on Android security features, which includes sandboxing and encrypted storage (depends on the Android version). Additional efforts should be tracked in
