(Xojo Plugin) PKCS7 Encrypt MIME

Encrypt MIME using a digital certificate to create PKCS7 encrypted S/MIME.

Chilkat Xojo Plugin Download

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

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim mime As New Chilkat.Mime

// Build a simple MIME message to be encrypted:
Dim success As Boolean
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"
