RSA Class

Represents the base class from which all implementations of the RSA algorithm inherit.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)
[ComVisibleAttribute(true)]
public abstract class RSA : AsymmetricAlgorithm

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.

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