In cryptography, CS-Cipher (for Chiffrement Symétrique) is a block cipher invented by Jacques Stern and Serge Vaudenay in 1998. It was submitted to the NESSIE project, but was not selected. The algorithm uses a key length between 0 and 128 bits (length must be a multiple of 8 bits). By default, the cipher uses 128 bits. It operates on blocks of 64 bits using an 8-round Feistel network and is optimized for 8-bit processors. The round function is based on the fast Fourier transform and uses the binary expansion of e as a source of "nothing up my sleeve numbers". (Wikipedia).
Compacting code with CSS variables
Click the SHOW MORE below for links to the demos (original & my fork) and more. Here, I'm compacting the code and making it more maintainable by eliminating defaults and using CSS variables to get rid of the `linear-gradient()` repetition. I'm not using Sass because the original pen wasn'
