(Excel) ConvertToSignedPk

Demonstrates how to digitally sign MIME to create an "opaque" signature. The MIME is converted to an application/x-pkcs7-mime which is a PKCS7 signature that includes both the original MIME message and the signature. This is different than AddDetachedSignaturePk, where the signature is appended to the MIME. This example demonstrates how to use the certificate and its corresponding private key when they are stored in separate files -- a .cer for the certificate, and a .pem for the private key.

Dim mime As Chilkat.Mime

' Convert the MIME to application/x-pkcs7-mime, which
' is PKCS7 containing both the original content and the signature.
success = mime.ConvertToSignedPk(cert,privKey)
If (success = False) Then
    Debug.Print mime.LastErrorText
    Exit Sub

Debug.Print "success!"
