Remarks

This algorithm supports key lengths of 128, 192, or 256 bits; defaulting to 256 bits. In .NET Framework, this algorithm supports block sizes of 128, 192, or 256 bits; defaulting to 128 bits (Aes-compatible). In .NET Core, it is the same as AES and supports only a 128-bit block size.

Important

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.
