SslStream.HashAlgorithm Property

Definition

Namespace:

System.Net.Security

Assembly:

System.Net.Security.dll

Source:

SslStream.cs

Gets the algorithm used for generating message authentication codes (MACs).

public:
 virtual property System::Security::Authentication::HashAlgorithmType HashAlgorithm { System::Security::Authentication::HashAlgorithmType get(); };

public virtual System.Security.Authentication.HashAlgorithmType HashAlgorithm { get; }

member this.HashAlgorithm : System.Security.Authentication.HashAlgorithmType

Public Overridable ReadOnly Property HashAlgorithm As HashAlgorithmType

Property Value

HashAlgorithmType

The algorithm used for generating message authentication codes (MACs).

Exceptions

InvalidOperationException

The HashAlgorithm property was accessed before the completion of the authentication process or the authentication process failed.

Examples

The following code example displays the cryptography settings for the specified stream.

static void DisplaySecurityLevel( SslStream^ stream )
{
   Console::WriteLine( L"Cipher: {0} strength {1}", stream->CipherAlgorithm, stream->CipherStrength );
   Console::WriteLine( L"Hash: {0} strength {1}", stream->HashAlgorithm, stream->HashStrength );
   Console::WriteLine( L"Key exchange: {0} strength {1}", stream->KeyExchangeAlgorithm, stream->KeyExchangeStrength );
   Console::WriteLine( L"Protocol: {0}", stream->SslProtocol );
}

static void DisplaySecurityLevel(SslStream stream)
{
   Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength);
   Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength);
   Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength);
   Console.WriteLine("Protocol: {0}", stream.SslProtocol);
}

Private Shared Sub DisplaySecurityLevel(stream As SslStream)
    Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength)
    Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength)
    Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength)
    Console.WriteLine("Protocol: {0}", stream.SslProtocol)
End Sub

Remarks

Message authentication algorithms generate message hashes and signatures used to detect tampering and forgery.
