Security Interface - Copy this React, Tailwind Component to your project

"Develop a security application that includes the following features: basic encryption/decryption algorithms (e.g., Caesar cipher, Substitution cipher, etc.), symmetric encryption, asymmetric encryption, hashing, and digital signatures. For features requiring cryptographic keys, allow users to either input an existing key or generate a new one if they don't already have one. Design the application to be modern, user friendly, and intuitive for seamless interaction."
