cryptographic systems

Cryptographic systems are methods used to protect information by transforming it into a secure format, ensuring only authorized parties can access or understand it. They use algorithms and keys—unique codes—to encrypt (hide) data so it can only be decrypted (revealed) with the correct key. Think of encryption as locking a message in a digital safe, and decryption as using the right key to open it. These systems protect privacy, secure communications, and verify identities in digital transactions, making them essential for maintaining confidentiality and trust in the digital world.
