On device #1 no constraint for my purpose. On the smartcard, the tradeoff is
between using EEPROM (plenty + slow + small life expectancy) for temp
variables versus RAM (very little) ... but I do not think it is an issue
eather in my case. Speed is what worries me most (crypto takes time).

But so far so good.
