AsymmetricKeyExchangeDeformatter.SetKey Method

When overridden in a derived class, sets the private key to use for decrypting the secret information.

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

public abstract void SetKey(
	AsymmetricAlgorithm key
)

Parameters

key
Type: System.Security.Cryptography.AsymmetricAlgorithm
The instance of the implementation of AsymmetricAlgorithm that holds the private key.

You must set a key before calling a DecryptKeyExchange implementation.

The following code example demonstrates how to override the SetKey to set the public key for encryption operations. This code example is part of a larger example provided for the AsymmetricKeyExchangeDeformatter class.


public override void SetKey(AsymmetricAlgorithm key) 
{
    if (key != null) 
    {
        rsaKey = (RSA) key;            }
    else 
    {
        throw new ArgumentNullException("key");
    }
}
