Constructors

	Name	Description
	RSAOAEPKeyExchangeFormatter()	Initializes a new instance of the RSAOAEPKeyExchangeFormatter class.
	RSAOAEPKeyExchangeFormatter(AsymmetricAlgorithm^)	Initializes a new instance of the RSAOAEPKeyExchangeFormatter class with the specified key.

Properties

	Name	Description
	Parameter	This API supports the product infrastructure and is not intended to be used directly from your code. Gets or sets the parameter used to create padding in the key exchange creation process.
	Parameters	This API supports the product infrastructure and is not intended to be used directly from your code. Gets the parameters for the Optimal Asymmetric Encryption Padding (OAEP) key exchange.(Overrides AsymmetricKeyExchangeFormatter::Parameters.)
	Rng	Gets or sets the random number generator algorithm to use in the creation of the key exchange.

Methods

	Name	Description
	CreateKeyExchange(array<Byte>^)	Creates the encrypted key exchange data from the specified input data.(Overrides AsymmetricKeyExchangeFormatter::CreateKeyExchange(array<Byte>^).)
	CreateKeyExchange(array<Byte>^, Type^)	Creates the encrypted key exchange data from the specified input data.(Overrides AsymmetricKeyExchangeFormatter::CreateKeyExchange(array<Byte>^, Type^).)
	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 it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (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(AsymmetricAlgorithm^)	Sets the public key to use for encrypting the key exchange data.(Overrides AsymmetricKeyExchangeFormatter::SetKey(AsymmetricAlgorithm^).)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

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

Use RSAOAEPKeyExchangeDeformatter to receive the key exchange and extract the secret information from it.

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.
