Crytography

Cryptography is the science of protecting information by transforming it into a secure format that can only be read by those who possess the right key. Mathematically, it involves complex algorithms and functions that encrypt (scramble) data and decrypt (unscramble) it using specific keys. This ensures confidentiality, integrity, and authentication of information, making it crucial for secure communication in areas like online banking and messaging. By applying mathematical principles, cryptography protects our digital lives from unauthorized access and ensures that sensitive information remains private.
