Kunkun

Demo

In the demo video below, I discussed the following:

  • What is Kunkun?
  • Why was is created?
    • Open Source
    • Cross-platform
    • Security and Privacy (achieved with a strict permission model)
    • More flexible (with web technologies, like Svelte)
  • How to use it?

Installation

Download Kunkun’s installer from https://kunkun.sh/download.

On Mac, if it asks for password to access keychain, you can select "Always Allow". I will explain.

It uses system keychain to store a randomly generated password to encrypt sqlite database, instead of using the same encryption key on everyone’s machine. Storing the password in a regular file would be a security risk. Even with obfuscation or encryption, it’s still possible to reverse engineer the binary to get the password. System keychain is the most secure way to store the password, but requires user to enter password when the app updates.
