Rijndael Class

Updated: August 2010

Represents the base class from which all implementations of the Rijndael symmetric encryption algorithm must inherit.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public abstract class Rijndael extends SymmetricAlgorithm

This algorithm supports key lengths of 128, 192, or 256 bits.

The Rijndael class is the predecessor of the Aes algorithm. You should use the Aes algorithm instead of Rijndael. For more information, see the entry The Differences Between Rijndael and AES in the .NET Security blog.

The following code example uses the Rijndael class to encrypt and then decrypt data.

No code example is currently available or this language may not be supported.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
