Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

Using this class, you can perform the following operations with e-mail messages:

• Encrypt or decrypt e-mails
• Sign e-mails with a digital signature
• Verify signatures of e-mails

Note   To use this class, make sure MailBee.NET Security Powerup is licensed (see LicenseKey property for details).

Example

This sample retrieves the last e-mail from the specified POP3 account, decrypts it if it's encrypted and verifies its signature if any. Then, it prints the plain-text version of the message to the console.

[C#]
// To use the code below, import these namespaces at the top of your code
using System;
using MailBee;
using MailBee.Pop3Mail;
using MailBee.Mime;
using MailBee.Security;

Smime objSmime = new Smime();
Pop3 pop = new Pop3();
pop.Connect("server", 110, true);
pop.Login("login", "password");
MailMessage msg = pop.DownloadEntireMessage(pop.InboxMessageCount);
pop.Disconnect();

try
{
    if (msg.IsEncrypted)
    {
        SmimeResult smResult = objSmime.DecryptAndVerify(msg, MessageVerificationFlags.All);
        if (smResult.VerificationResult > 0)
        {
            Console.WriteLine("Verification failed");
        }
        else if (smResult.DecryptedMessage != null)
        {
            Console.WriteLine(smResult.DecryptedMessage.BodyPlainText);
        }
    }
}
catch (MailBeeException ex)
{
    Console.WriteLine(ex.Message);
}

        ElseIf (Not IsNothing(smResult.DecryptedMessage)) Then
            Console.WriteLine(smResult.DecryptedMessage.BodyPlainText)
