An asymmetric algorithm is one where the sender and the recipient do not share the same knowledge (i.e. only one party knows the secret key). All asymmetric algorithm implementation classes inherit from this abstract class. Implementations are instantiated using the Create( ) method, which accepts the name of an implementation as a String argument; the default implementation class is created if no name is specified; the system administrator determines the default class.

The LegalKeySizes property returns an array of the KeySizes class, specifing the set of key lengths supported by an implementation class. The KeySize property gets or sets the key length. ...
