 BEAR and LION ciphers

BEAR and LION are two symmetric block cipher algorithms developed for encryption purposes, primarily used in scenarios where security is paramount. Here’s a brief overview of each: ### BEAR Cipher - **Overview**: BEAR (Bitwise Efficient And Rapid) is a stream cipher designed with efficiency and lightweight operations in mind. It aims to provide robust security features while being computationally efficient for devices with limited processing power, like embedded systems.
