RSAPKCS1KeyExchangeFormatter Class

Creates the PKCS#1 key exchange data using RSA.


Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public class RSAPKCS1KeyExchangeFormatter : AsymmetricKeyExchangeFormatter

The RSAPKCS1KeyExchangeFormatter type exposes the following members.

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.

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.

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 (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.
