ESP32 Forum

Greetings, everyone.
Let me introduce you to Midbar.
Midbar combines in it a password vault, credit card vault, and some other features.

Aside from what I mentioned above, Midbar has other useful features, such as:

• PS/2 keyboard support - Allows you to interact with Midbar using the PS/2 keyboard connected to the ESP32;

• RFID-lockable (four RFID cards + master password to be exact) - Midbar is locked with a combination of four RFID cards and a master password (It's about the Midbar V4.0, not Midbar V5.0);

• Ease of data backup - Allows you to back up your data by simply copying it from the SD card (It's about the Midbar V5.0, not Midbar V4.0);

• Sophisticated encryption with integrity verification - Midbar utilizes a 3DES + AES + Blowfish + Serpent Encryption Algorithm in the cipher block chaining mode of operation combined with the HMAC-SHA256 to encrypt your data and check its integrity to keep your data safe;

• Data Hasher - You can use Mudbar to hash a string using the SHA-256 or SHA-512 hash functions.

If you're interested in this project, you can read the tutorials for Midbar V4.0 and Midbar V5.0 here:

P.S. I forgot to mention another pro of Midbar - Some versions of Midbar that came after the Midbar V2.5 (including the Midbar V4.0 and Midbar V5.0) have multiple lock screens. Here are some of them.

You can also play with the simulation of Midbar V5.0 on Wokwi.
