(Layman's terms please, I'm just a kid stuck on a puzzle)
I'm trying to factor the following RSA256 public key to find the corresponding private key:
I got as far as downloading a YAFU factorization program found here, which I was told is capable of factoring such a key in 103 seconds on a core i7. This program works great for factoring base 10 numbers, but I have no idea how to use it on a RSA key. Any help would be hugely appreciated. Thanks!
