ToothPaste: encrypted BLE dongle for pushing data to air-gapped machines

Brisk4t built ToothPaste, a Bluetooth Low Energy dongle that lets you securely paste text or data onto air-gapped devices without breaking their network isolation. For developers and security-minded makers who manage isolated systems, it's a practical alternative to sneakernet USB transfers. The encrypted channel means you're not just punching a hole in your air gap — you're doing it with some protection.
