ToothPaste is a hardware-backed BLE clipboard dongle that lets users securely paste encrypted keyboard and mouse commands to any USB device, including air-gapped systems, via a web browser. It combines an ESP32-S3 with a cryptographic coprocessor for AES-256 encryption, offering a unique blend of wireless convenience and hardware security for one-off password entry or data transfer. The project's innovative use of Web-BLE and a secure element to solve a common pain point makes it interesting for security-conscious users and tinkerers.

Target audience: security engineers, hobbyists, sysadmins
