Pop3ClientSslHashAlgorithm Property

Get the negotiated SSL or TLS hash algorithm.

Namespace: MailKit.Net.Pop3
Assembly: MailKit (in MailKit.dll) Version: 4.7.1
Syntax
C#
public override HashAlgorithmType? SslHashAlgorithm { get; }

Property Value

NullableHashAlgorithmType
The negotiated SSL or TLS hash algorithm.

Implements

IMailServiceSslHashAlgorithm
IMailServiceSslHashAlgorithm
Remarks
Gets the negotiated SSL or TLS hash algorithm once an SSL or TLS connection has been made.
Example
C#
public static void PrintSslConnectionInfo (string host, int port)
{
    using (var client = new SmtpClient ()) {
        client.Connect (host, port, SecureSocketOptions.Auto);

        Console.WriteLine ($"Negotiated the following SSL options with {host}:");
        Console.WriteLine ($"        Protocol Version: {client.SslProtocol}");
        Console.WriteLine ($"        Cipher Algorithm: {client.SslCipherAlgorithm}");
        Console.WriteLine ($"         Cipher Strength: {client.SslCipherStrength}");
        Console.WriteLine ($"          Hash Algorithm: {client.SslHashAlgorithm}");
        Console.WriteLine ($"           Hash Strength: {client.SslHashStrength}");
        Console.WriteLine ($"  Key-Exchange Algorithm: {client.SslKeyExchangeAlgorithm}");
        Console.WriteLine ($"   Key-Exchange Strength: {client.SslKeyExchangeStrength}");

        // Example Log:
        // 
        // Negotiated the following SSL options with pop.gmail.com:
