This article explains, poorly, _what_ public key cryptography is but not _how_ public key cryptography really works, at all.
Saying that Natasha and Boris both choose a prime number and then "create a safe" with it, is the same as telling someone that to make cake Alice and Bob went to the store and bought flour and eggs.
If you want a real, good and visual explanation of _how_ it works, with simple maths, go watch Computerphile's video[0] about Diffie-Hellman.

- x3y1 2y agoI really liked the book “Implementing SSL / TLS Using Cryptography and PKI”. When trying to understand certificates and TLS, there always seemed to be some tricky bits that most explanations glossed over. In this book, the author builds a working TLS implementation in C, which means they have to cover all the details.
