From the project
A standalone elliptic curve/AES file encryption and decryption device
The ParanoiaBox is a standalone open hardware/software encryption device based on the STM32F103CBT6 processor. On this device, messages may be composed, encrypted, decrypted, and viewed. The device is an experiment in encryption minimalism, presenting a minimal attack surface by using a small microcontroller rather than a full personal computer with a complex operating system, while providing the functionality needed to transact encrypted messages between humans through insecure networks. The device is connected to a NTSC television and a PS/2 keyboard for user input and control. There are…
