After making the Midbar Firebase Edition V2.0, I realized that even though it's a fully functional vault synced with the desktop app, it's still insufficient. For starters, it only allows the user to store login credentials on it, not to mention that the desktop app provided with that version was raw and a bit slow as it had to load the whole record from the Google Firebase and not just its title, in other words, there was no preview function. In addition to that, the hardware vault utilized a small 160x128 screen and couldn't emulate the USB keyboard. To negate these flaws, I took Midbar V6.0 as the base, replaced the encryption algorithm, and modified it to utilize the Google Firebase as the filesystem. I also made a new desktop app that enables users to work not just with login credentials but also with credit card details, notes, and phone numbers. The desktop app provided in that version only loads the whole record when it's being viewed or edited, allowing faster movement between the slots in the main menu.

This version of Midbar stores the encrypted data in the cloud while keeping the cryptographic keys on the edge!

Thanks. The second pic looks so beautiful.

Thank you. I'm glad you liked it.

The string encryption software compatible with Midbar (Teensy 4.1) V3.1, Midbar ESP32 CYD, and Midbar ESP32-CYD Firebase Edition is now available as a web app.

Check it out in the "String Encryption" -> "Midbar-Compatible AES-256 CBC" tab at https://northstrix.github.io/React-Cryp ... c-Toolkit/

Great update! Love the addition of credit card and note support. The faster navigation is a huge plus too. Looking forward to trying it out!
