I was a little quick on sending my previous email. The explanation is: the modulus that be factored by considering it as a polynomial of base 2^160 and using standard algebra software.
one of the factors is 3*2^1022 + 3*2^518 + 5*2^344 + 3 On Sat, Dec 3, 2022 at 8:29 PM Matthew McPherrin <[email protected]> wrote: > The certificate has been revoked and replaced by the subscriber. > > The private key has been factored by remy_o, who says: > > > the modulus that be factored by considering it as a polynomial of base > 2^160 and using standard algebra software > > On Sat, Dec 3, 2022 at 2:48 PM Hanno Böck <[email protected]> wrote: > >> Hi, >> >> I'm not entirely sure if this is the right place to discuss this, but >> I also don't really know where else. >> >> Do people have thoughts about suspicious keys like this? >> https://crt.sh/?id=8093628131 >> (Have a look at the modulus / N value, it has a lot of zeros) >> >> This key is certainly not securely generated.
