[VB6 equivalent: CMS_MakeDetachedSig]

Dim nRet As Integer

' First, Alice reads her private key into a string
strPrivateKey = Rsa.ReadPrivateKey(strEPKFile, "password").ToString()
If strPrivateKey.Length = 0 Then
    Console.WriteLine("Cannot read private key")
    Exit Sub
End If

' Alice makes a detached signature using
' the hash of the content and her private key
nRet = Cms.MakeDetachedSig(strOutFile, strHexDigest, _
    strCertFile, strPrivateKey, HashAlgorithm.Sha1, 0)
Console.WriteLine("CMS_MakeDetachedSig returns " & nRet)
