Extending this class proves that you are implementing an RSA key. This is required for any developer providing a new RSA key implementation.

The only purpose of this class is as a hierarchy member for identification of the RSA algorithm.

The RSACryptoServiceProvider supports key lengths from 384 bits to 16384 bits in increments of 8 bits if you have the Microsoft Enhanced Cryptographic Provider installed. It supports key lengths from 384 bits to 512 bits in increments of 8 bits if you have the Microsoft Base Cryptographic Provider installed.
