Hey man love the vids. I am in engineering school and I love learning about this stuff. Could it be possible that the solution to the reimann hypothesis is a "decrypter" for massive prime numbers allowing anyone to read private information? I can understand from the physics side why the hypothesis is wanted to be solved but I can't really think of any real world applications.

+Fizz My first reaction was that there is no link between the Riemann hypothesis (by the way I have a video on that Intro Riemann hypothesis - YouTube ) and factoring huge numbers into its prime divisors. I have spoken with 2 colleagues who do research in the prime number theorem and computational number theory and neither know of any link.There is a primality testing algorithm and an algorithm to find the least quadratic nonresidue modulo p that are improved if the Generalised Riemann hypothesis is true. In practice these algorithms are not often used as there are better randomised algorithms. Bottom line...it could be possible but does not seem to be presently known.

Nice video and metaphor but RSA encryption is not "double" encryption, authentication is checked by encryption a "signature" with the private key

Andrew Meyer commented on 15 Oct 2015
+Drake B Eh, close enough. For RSA at least, the signature is just a hash of the message encrypted with the sender's private key. Having to explain all that though would just complicate the analogy, and doesn't really add any important information for the average person.

That would more come under the lines of how to build an encryption. this is just showing fundamentals of how the process works and explaining that an encryption is just a hidden value that can be uncovered by a unique system.
