  NameDescription
Public propertyParameterInfrastructure. Gets or sets the parameter used to create padding in the key exchange creation process.
Public propertyParametersInfrastructure. Gets the parameters for the Optimal Asymmetric Encryption Padding (OAEP) key exchange. (Overrides AsymmetricKeyExchangeFormatter.Parameters.)
Public propertyRngGets or sets the random number generator algorithm to use in the creation of the key exchange.

  NameDescription
Public methodCreateKeyExchange(Byte[])Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter.CreateKeyExchange(Byte[]).)
Public methodCreateKeyExchange(Byte[], Type)Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter.CreateKeyExchange(Byte[], Type).)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSetKeySets the public key to use for encrypting the key exchange data. (Overrides AsymmetricKeyExchangeFormatter.SetKey(AsymmetricAlgorithm).)
Public methodToStringReturns 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 noteCaution:

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.
