me too, Michael.
In fact, I even cannot still understand the main problem of the original poster. If he uses ASM so CJNE is not a surprise for him.
Another question is how store predefined password(s). I asked about chip he used, but no answer yet.
BTW, has anybody used PGP or other public-key based cipher alhorithms? I know that some high-security parts provide us with user x-bytes array of external placed program decoding but have never used it. Is it really hard to configure and use?

Thanks,
Oleg
