EncryptLens vs BI Data Hero

EncryptLens is an educational app designed to make the core principles of cryptography accessible and engaging. With an intuitive, interactive interface, users can explore four major encryption techniques: Caesar Cipher: Shift letters of the alphabet and see how small changes affect message security. Substitution Cipher: Customize letter mappings to create unique encryption keys and discover the challenge of decryption without the key. RSA Encryption: Follow the process of key generation and observe how asymmetric encryption transforms messages for secure communication. Hashing: Enter text and see how different algorithms generate unique hash outputs, demonstrating concepts like the avalanche effect and hash collisions. Each section is crafted to spark curiosity and enhance understanding through hands-on, visual experiences. Ideal for students, security enthusiasts, and anyone interested in how data protection works in the digital world.
