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

public override byte[] CreateKeyExchange (
	byte[] rgbData
public byte[] CreateKeyExchange (
	byte[] rgbData
public override function CreateKeyExchange (
	rgbData : byte[]
) : byte[]
Not applicable.



The secret information to be passed in the key exchange.

Return Value

The encrypted key exchange data to be sent to the intended recipient.

Exception typeCondition


The key is missing.

This data can be interpreted only by the holder of the private key corresponding to the public key used to encrypt the data. This helps to ensure that only the intended recipient can access the secret information.

The following code example demonstrates how to use the CreateKeyExchange method to encrypt the specified message. This code example is part of a larger example provided for the RSAOAEPKeyExchangeFormatter class.

byte[] byteMessage = Encoding.ASCII.GetBytes(message);
encodedMessage = keyEncryptor.CreateKeyExchange(byteMessage);

ubyte byteMessage[] = Encoding.get_ASCII().GetBytes(message);
encodedMessage = keyEncryptor.CreateKeyExchange(byteMessage);
