Hi there,

In 2008, we tried USB Token implementation for GnuPG with Atmel AVR.
It worked a little.  It was 8-bit processor with no USB controller
and it was not for real use.

This year, I am trying to build a new version with STM32.  I named
the software "Gnuk", and initial version is at:


It uses ChibiOS/RT, and uses polarSSL for RSA computation.

For hardware, I am using STM32-H103 board by Olimex:


Currently, it only supports RSA 2048-bit digital signature.

With Gnuk, I am learning OpenPGP card protocol version 2.

Today, I just put a tar ball.  We will have Git repository soon.
