Cryptography

Cryptography, or cryptology is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

We have sniffed an unsecured network and found numbers that are used to encrypt very important documents. It seems that those numbers are not always generated using large enough prime numbers. Your mission should you choose to accept it, is to factorize these numbers as fast as possible before the target fixes this bug on their server - so that we can decode the encrypted documents.
