Chilkat Xojo Plugin Download

Xojo Plugin for Windows, Linux, Mac OS X, and ARM

Dim mime As New Chilkat.Mime

Dim success As Boolean
success = mime.UnlockComponent("Anything for 30-day trial.")
If (success = False) Then
    System.DebugLog(mime.LastErrorText)
    Return
End If

//  Build a simple MIME message to be encrypted:
success = mime.AddHeaderField("Content-Type","text/plain")
success = mime.AddHeaderField("abc","123")
mime.SetBody "This is a test"

//  A digital certificate is required to create PKCS7 encrypted MIME.
//  It can come from a variety of sources: .cer file, .pfx file, PEM files,
//  an in-memory representation, or directly from a Windows
//  registry-based certificate store.

//  This example will load a certificate object from a .cer file.
//  Note: Only the public-key is required to encrypt.  (Decryption
//  requires a private key.)

Dim cert As New Chilkat.Cert
success = cert.LoadFromFile("myCert.cer")
If (success = False) Then
    System.DebugLog(cert.LastErrorText)
    Return
End If

//  Encrypt the MIME:
success = mime.Encrypt(cert)
If (success = False) Then
    System.DebugLog(mime.LastErrorText)
    Return
End If

//  Display the MIME:
System.DebugLog(mime.GetMime())

//  The resulting S/MIME looks something like this:

/*
abc: 123
Content-Disposition: attachment; filename="smime.p7m";
Content-Transfer-Encoding: base64
Content-Type: application/x-pkcs7-mime;
 name="smime.p7m";
