What a pointless article. Not only doesn&#x27;t it get into the interesting side-effects of choosing Mersenne primes as your private key (which is <i>actually</i> interesting, as the bit pattern of a*b is very apparent when you multiple two Mersenne primes). The whole thing is just talking about &quot;don&#x27;t use this shiny new prime because people will notice that you have very long public keys&quot;. It glosses over how key generation actually works, and I really don&#x27;t understand why the author felt like wasting people&#x27;s time with such lack of content.
