Syntax

C++

[ComVisibleAttribute(true)]
public ref class RSAPKCS1KeyExchangeDeformatter : AsymmetricKeyExchangeDeformatter

Constructors

	Name	Description
	RSAPKCS1KeyExchangeDeformatter()	Initializes a new instance of the RSAPKCS1KeyExchangeDeformatter class.
	RSAPKCS1KeyExchangeDeformatter(AsymmetricAlgorithm^)	Initializes a new instance of the RSAPKCS1KeyExchangeDeformatter class with the specified key.

Properties

	Name	Description
	Parameters	Gets the parameters for the PKCS #1 key exchange.(Overrides AsymmetricKeyExchangeDeformatter::Parameters.)
	RNG	Gets or sets the random number generator algorithm to use in the creation of the key exchange.

Methods

	Name	Description
	DecryptKeyExchange(array<Byte>^)	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 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 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 (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.

Use RSAPKCS1KeyExchangeFormatter to create the key exchange message using 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.

Examples

The following example shows how to use the RSAPKCS1KeyExchangeDeformatter class to recreate an exchange key to be used to decrypt a message.
