Mini Diarium
An encrypted, local cross-platform journaling app
Mini Diarium keeps your journal private. Every entry is encrypted with AES-256-GCM before it touches disk, the app never connects to the internet, and your data never leaves your machine. Built with Tauri, SolidJS, and Rust.
Background
Mini Diarium is a spiritual successor to Mini Diary by Samuel Meuli. I loved the original tool. It was simple, private, and did exactly what a journal app should do. Unfortunately, it's been unmaintained for years and its dependencies have aged out. I initially thought about forking it and modernizing the stack, but turned out impractical. So I started over from scratch, keeping the same core philosophy (encrypted, local-only, minimal) while rebuilding completely with Tauri 2, SolidJS, and Rust. The result is a lighter, faster app with stronger encryption and a few personal touches.
Features
Key file authentication : unlock your diary with an X25519 private key file instead of (or alongside) your password, like SSH keys for your journal. Register multiple key files; manage all auth methods from Preferences. See Key File Authentication for details.

See Key File Authentication for details. AES-256-GCM encryption : all entries are encrypted with a random master key. Each auth method holds its own wrapped copy of that key, so adding or removing a method is O(1), with no re-encryption of your entries.
