Methods

  Name Description
Public methodSupported by Silverlight for Windows Phone CreateKeyExchange(array<Byte[]) Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter.CreateKeyExchange(array<Byte[]).)
Public methodSupported by Silverlight for Windows Phone CreateKeyExchange(array<Byte[], Type) Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter.CreateKeyExchange(array<Byte[], Type).)
Public methodSupported by Silverlight for Windows Phone Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone 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.)
Public methodSupported by Silverlight for Windows Phone GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone GetType Gets the Type of the current instance. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows Phone MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows Phone SetKey Sets the public key to use for encrypting the key exchange data. (Overrides AsymmetricKeyExchangeFormatter.SetKey(AsymmetricAlgorithm).)
Public methodSupported by Silverlight for Windows Phone 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 RSAPKCS1KeyExchangeDeformatter to receive the key exchange and extract the secret information from it.

Caution noteCaution:

We recommend that you do 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.
