Respectively they are 'K', 'DI' and 'P', which represent snKey, DeviceIdentifier (related with your machine), Platform (Appropriately speaking, it should be OS Type). It is just a JSON-style ASCII string which contains 3 items. It is a Base64 string that represents 256-bytes-long data, while the 256-bytes-long data is the cipher text of the offline activation information encrypted by Navicat Activation Public Key. You can see it by searching string '-BEGIN PUBLIC KEY- '. Instead, the public key is stored in Navicat executable file Navicat Premium.app/Contents/MacOS/Navicat Premium.

Start from Navicat Premuim 12.0.24 for Mac, the public key is no longer stored in Navicat Premium.app/Contents/Resources/rpk. I would be very appreciated for your generous.

If you have the corresponding private key, please tell me.
