Cryptography is the practice and study of techniques for secure communication, ensuring that only the intended recipient can read the message by converting it into an unreadable format (ciphertext) and back to readable format (plaintext) using a secret key. It plays a crucial role in modern cybersecurity, protecting sensitive information from unauthorized access and ensuring data integrity and confidentiality.
