Just got this link from a friend: http://gas.dia.unisa.it/projects/jlbc/schemes/bgv11.html

It is based on RLWE encryption angorythms. If I can somehow get the code to go open source, I can use it in Stag so that it will continue to be safe even after the release of quantum computing...

EDIT: Ah ha! It is open source... Just found the repository. Will be implementing it instead of sha256.

EDIT 2: Hmmm.. This encryption algorythm seems to take an awful long time to execute even with the most basic settings. In other words... Public/private key generation will take a while. I wonder if there is any way to speed up the process by providing fixed numbers rather than relying on a generator to come up with a prime number for me...

Edit 3: it took some searching, but I finally found a list of prime numbers that contains a large number of 64 bit primes. This is promising. It contains the first  1.4 billion prime numbers.
