This video features Dr James Grime (http://singingbanana.com/). Message from James: "Thanks to Dr Chris Hughes of the University of York who showed me how to find the RSA public key from my browser, and showed me how awesome they look when you print them out."

Regarding the keys used for encryption:
x, y prime
Encode key E shares no factors with (x-1)(y-1)
Decode key is D with E*D - 1 a multiple of (x-1)(y-1)
