I’m left with the impression todays code signing is not all that’s its cracked up to be.
For starters, where a prime number is used in encryption, whilst in theory primes are infinite, in practice, a pc only has a few milliseconds to come up with one. Let that sink in for a moment!
With that in mind, the range of primes available for encryption algo’s to use is heavily restricted by time, making cracking an algo something akin to fine tuned brute forcing imo.
