You absolutely SHOULD roll your own crypto
Expert cryptographers will warn you to never roll your own algorithms. Well, they’re wrong and here are three reasons why.

Basic cryptography – the Vigenere cipher
The Vigenere cipher is more complicated that the Caesar cipher but based on the same idea. It uses a running key to keep your message secure.

Different cipher types
Anyone studying cryptography needs to understand various forms of ciphers. Today, we’ll look at three that you should know well.

Basic cryptography – the Caesar cipher
One of the most basic encryption schemes is the Caesar cipher. It’s weak in practice, but a great way to learn how crypto works.

Modulo arithmetic with large numbers
Modulo arithmetic with numbers large enough to ensure cryptographic security is complicated, particularly in PHP. Let’s work around that…
