Modern Cryptography

Modern cryptography is the science of securing information through complex mathematical methods, ensuring that data remains private and unaltered. It involves techniques like encryption, which transforms readable data into scrambled code, and decryption, which restores it to its original form for authorized users. Cryptography also includes methods for verifying identities and ensuring data integrity. These processes protect sensitive information—such as personal details, financial transactions, and communications—from unauthorized access and tampering, enabling secure digital interactions in our connected world.
