• For idiots like myself, I found this video, Public key cryptography - Diffie-Hellman Key Exchange (full version), to be completely enlightening using mixed colors to explain the most basic features of a cryptography algorithm.[0] [0] [VIDEO]

• Interesting, thanks for sharing (I too was curious). This is my favorite video on Diffie-Hellman key exchange which is a slightly different problem (sharing a secret, without the constraint of dividing the key): [VIDEO] (oh, hey, same channel! Guess I'll need to check out more …

• This is the only video that ever explained it concisely and clearly, IF you don't care about trying to actually implement it: [VIDEO]
