Rijndael

Rijndael is a sophisticated encryption algorithm used to secure both data and communications. It works by transforming plaintext (original information) into encrypted data (ciphertext) through a series of complex mathematical steps, making it unreadable without a special key. Developed by Joan Daemen and Vincent Rijmen, Rijndael was chosen as the basis for Advanced Encryption Standard (AES) in 2001, which is widely used for protecting sensitive information. Its strength lies in its ability to efficiently handle data in blocks and perform multiple layers of transformations, ensuring high security against unauthorized access.
