Rijndael and Rijndael Managed are two classes of cryptography namespaces. Rijndael is a type of symmetric algorithm, and it is the oldest method of encryption in transmitting, collecting digital information, and storing digital data.
Other examples of symmetric algorithms include DES, Triple DES, RC2, and AES. Different symmetrical algorithms have their corresponding applications, and Rijndael is the base class of the Rijndael algorithm, and it is an abstract public class.
It may also be depicted as inheritable, and it cannot be directly insatiable. It is a type of encryption algorithm, and its main job is to keep data safe, authenticated, private, and secure as it is passed from one user to another.
