The RSAPKCS1KeyExchangeFormatter type exposes the following members.

  NameDescription
Public methodRSAPKCS1KeyExchangeFormatter()Initializes a new instance of the RSAPKCS1KeyExchangeFormatter class.
Public methodRSAPKCS1KeyExchangeFormatter(AsymmetricAlgorithm)Initializes a new instance of the RSAPKCS1KeyExchangeFormatter class with the specified key.

  NameDescription
Public propertyParametersGets the parameters for the PKCS #1 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(array<Byte>)Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter::CreateKeyExchange(array<Byte>).)
Public methodCreateKeyExchange(array<Byte>, Type)Creates the encrypted key exchange data from the specified input data. (Overrides AsymmetricKeyExchangeFormatter::CreateKeyExchange(array<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 it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (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 (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.

The following example shows how to use the RSAPKCS1KeyExchangeFormatter class to create an exchange key for a message recipient.
