Then output encrypted public key with format '%s%d%s%d%s'.

The following content is discovered from libcc.dll of Navicat Premium 圆4 12.0.25 Simplified Chinese version. To avoid being replaced easily, the public key is split into 5 parts: Instead, the public key is stored in libcc.dll and has been encrypted. Start from Navicat Premium 12.0.25, Navicat do not load this public key from resource in navicat.exe. I would be very appreciated for your generous. If you have the corresponding private key, you can tell me.

You can see it by a software called Resource Hacker. It is stored in navicat.exe as a kind of resource called RCData. It is a RSA-2048 public key that Navicat used to encrypt or decrypt offline activation information.
