modern encryption techniques

Modern encryption techniques secure information by transforming readable data into an unreadable format using complex algorithms and keys. Symmetric encryption uses the same key for both locking (encrypting) and unlocking (decrypting) data, making it efficient for large data. Asymmetric encryption employs a pair of keys—one public, one private—where the public key encrypts data and the private key decrypts it, enabling secure communication without sharing secrets. These methods ensure that only authorized parties can access the information, protecting sensitive data from unauthorized access during transmission or storage.
