No. No. No.
Just...no.
We know,
a priori, from derrek & co that their estimate for the time to brute force the sighax signature using 10 CPUs and all the optimizations they could think of was
6 months.
We also know, via calculations on how fast we can do modular exponentiations on PC, this equates to
about 2^50 signatures to check, using PERFECT code on PC.
This equates to
300 million years, at your claimed rate of ~10000 signatures/day.
The specifics of why your math is wrong is you're assuming generating the signatures to check takes zero time -- it takes a LOT of exponentiations to generate any signatures that even MIGHT be valid. ~16 bits for the 00 02 prefix, and then way more for the ASN.1 structure, since you're not overflowing the first length tag -- many of those must be valid, too, and we
don't know which ones.
So, no,
bruteforcing sighax is not possible without the bootroms.
@addi33 - Please update the OP to note that it's not possible,
@Selver is wrong.
