Example

[Visual Basic, C#] The following example demonstrates how to verify signed email and decrypt encrypted email with EAGetMail POP3 & IMAP4 Component. To get the full samples of EAGetMail, please refer to Samples section.

[Visual Basic]
Dim oMail As New Mail("TryIt")
oMail.Load("c:\test.eml, False)

If (oMail.IsEncrypted) Then
    Try
        ' this email is encrypted, we decrypt it by user default certificate.
        ' you can also use specified certificate like this
        ' Dim oCert As New Certificate()
        ' oCert.Load("c:\test.pfx", "pfxpassword", Certificate.CertificateKeyLocation.CRYPT_USER_KEYSET)
        ' oMail = oMail.Decrypt( oCert )
        oMail = oMail.Decrypt(Nothing)
    Catch ep As Exception
        MessageBox.Show(ep.Message)
    End Try
End If

If (oMail.IsSigned) Then
    Try
        'this email is digital signed.
        Dim cert As EAGetMail.Certificate = oMail.VerifySignature()
        MessageBox.Show("This email contains a valid digital signature.")
        'you can add the certificate to your certificate storage like this
        'cert.AddToStore( Certificate.CertificateStoreLocation.CERT_SYSTEM_STORE_CURRENT_USER,"addressbook" );
        'then you can use send the encrypted email back to this sender.
    Catch ep As Exception
        MessageBox.Show(ep.Message)
    End Try
End If

[C#]
Mail oMail = new Mail("TryIt");
oMail.Load( "c:\\test.eml", false );

if( oMail.IsEncrypted )
{
    try
    {
        //this email is encrypted, we decrypt it by user default certificate.
        // you can also use specified certificate like this
        // Certificate oCert = new Certificate();
        // oCert.Load("c:\test.pfx", "pfxpassword", Certificate.CertificateKeyLocation.CRYPT_USER_KEYSET)
        // oMail = oMail.Decrypt( oCert );
        oMail = oMail.Decrypt( null );
    }
    catch(Exception ep )
    {
        MessageBox.Show( ep.Message );
    }   
}

if( oMail.IsSigned )
{
    try
    {
        //this email is digital signed.
        EAGetMail.Certificate cert = oMail.VerifySignature();
        MessageBox.Show( "This email contains a valid digital signature.");
        //you can add the certificate to your certificate storage like this
        //cert.AddToStore( Certificate.CertificateStoreLocation.CERT_SYSTEM_STORE_CURRENT_USER,
        //  "addressbook" );
        // then you can use send the encrypted email back to this sender.
    }
    catch(Exception ep )
    {
        MessageBox.Show( ep.Message );
    }
