If you can help I'll extract the public certificate and post it here asap.
I think that a tool to calculate the 8 ecc_curve_array[] parameters will be AMAZING

You want to break 4 113 bit's ECC curves by solving ECDSA?
We used like 6 months last time so unless you have access to a lot of CPU's this will take forever.
