This is only a proof of concept cracking of a 22 bit RSA key. However it shows that the cracking of cryptographic algorithms that we are currently using require advances in technology rather than in theory or basic science. I suspect that the time we have before our current banking security is useless is a few decades, but there time before national agencies can crack messages protected by these algorithms a lot less

@h_bueler I haven't looked too deeply at the #cryotography, but yeah, it leaves several things to be desired. But it lifts the abysmal security of vanilla email way off the floor, and very cleverly leverages the "network effects" that widespread email usage already enjoys.

So yeah, no 100% score for encryption goodness, but isn't 80-ish % perfection a huge improvement over 0 ish %, with vanilla email? To me the glass is 80-ish % full, not 20% empty there. A welcome improvement.
