[ComVisibleAttribute(true)]
public class RSAOAEPKeyExchangeDeformatter : AsymmetricKeyExchangeDeformatter

The RSAOAEPKeyExchangeDeformatter type exposes the following members.

Constructors

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

Properties

	Name	Description
	Parameters	Gets the parameters for the Optimal Asymmetric Encryption Padding (OAEP) key exchange. (Overrides AsymmetricKeyExchangeDeformatter.Parameters.)

Top

Methods

	Name	Description
	DecryptKeyExchange	Extracts secret information from the encrypted key exchange data. (Overrides AsymmetricKeyExchangeDeformatter.DecryptKeyExchange(array<Byte[]).)
	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	Sets the private key to use for decrypting the secret information. (Overrides AsymmetricKeyExchangeDeformatter.SetKey(AsymmetricAlgorithm).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

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 RSAOAEPKeyExchangeFormatter to create the key exchange message with the RSA algorithm.

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.
