RSA Algorithm

RSA (Rivest–Shamir–Adleman) algorithm is an asymmetric cryptographic algorithm that is widely used in the modern public-key cryptosystems. We have been hearing RSA algorithm all the time, but some of us actually did not know what it really is and how it works.

In this article, I will systematically discuss the theory behind the RSA algorithm. The theory guarantees that the cryptosystems built on the top of the RSA algorithm are relatively safe and hard to crack, which is fundamentally interesting.

Pure HTML Share Buttons

Share buttons are a great way to make sharing content easier, leading to make engagement and visitors down the road. Unfortunately, most first-party share widgets are ugly and require loading external scripts. Yuck. Not only that, but many also install 3rd-party tracking cookies that invade the reader’s privacy.

Luckily, it’s possible to create your own share buttons using a single <a /> tag. The reason this is possible is because social networks need to provide methods of sharing that work inside of emails (email clients don’t execute JavaScript).
