Good to hear that. :-)

Err.. well, 1.2.4 was released last week.

I am now considering to port Chopstx to GNU/Linux, so that I can emulate
Gnuk without real hardware.  By the emulation, we can extend the
coverage of the GnuPG test suite.

And together with Achim Pietig, I am trying to add new KDF DO support to
Gnuk and scdaemon.  With this enhancement, a risk of the exposure of
flash ROM content can be minimized.  With new KDF DO support, KDF
computation can be also done in host side, mostly done in host side.
