Methods

	Name	Description
	CreateKeyExchange(array<Byte[])	When overridden in a derived class, creates the encrypted key exchange data from the specified input data.
	CreateKeyExchange(array<Byte[], Type)	When overridden in a derived class, creates the encrypted key exchange data from the specified input data.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SetKey	When overridden in a derived class, sets the public key to use for encrypting the secret information.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Asymmetric key exchange formatters encrypt key exchange data.

Key exchange allows a sender to create secret information, such as random data that can be used as a key in a symmetric encryption algorithm, and use encryption to send it to the intended recipient.

Caution:
It is highly recommended that you not attempt to create your own key exchange method from the basic functionality provided, because many details of the operation must be performed carefully in order for the key exchange to be successful.
