The Rijndael algorithm is a cryptographic encryption method developed by Belgian cryptographers Joan Daemen and Vincent Rijmen. This versatile algorithm was chosen by the National Institute of Standards and Technology (NIST) to construct the Advanced Encryption Standard (AES).

The AES encryption is considered a robust and secure encryption technique with key lengths of 128, 192, or 256 bits and a block length of 128 bits. Compared to Triple DES, AES key size is larger and can be encrypted in just one pass instead of three.

The NIST solicited advanced algorithms from cryptographers in the early months of 1997. As a result, the Rijndael symmetric block cipher method was selected in late 2000 from 21 submissions by 11 nations. The algorithm’s name is pronounced “rine-doll” and has been used widely in different applications such as wireless communications and data storage.
