indeed, it was trying to recompile muscletool, but running pcscd in
console, debug mode will be fine.

for SFM key: modulus (same as the one of public key) and private exponent.
for CRT key: p, q, dP, dQ & PQ
(dP & dQ could be named "reduced exponents" but it is the common rule)
if you only have p, q AND the public exponent e, one can compute
d = 1 / e mod (p - 1)(q - 1) -- the private exponant
dP = d mod (p - 1)
dQ = d mod (q - 1)
PQ = 1 / q mod p
