Dim fac As New CkFileAccess
Dim p7mBytes() As Byte
p7mBytes = fac.ReadEntireFile("testData/p7m/fattura_signature.p7m")
If (fac.LastMethodSuccess <> 1) Then
Debug.Print fac.LastErrorText
Exit Sub
End If
Dim crypt As New ChilkatCrypt2
Dim originalXml As String
originalXml = crypt.OpaqueVerifyString(p7mBytes)
If (crypt.LastMethodSuccess <> 1) Then
Debug.Print fac.LastErrorText
Exit Sub
End If
Debug.Print "Original XML:"
