' as needed when signing occurs.

' If you have CA certs located elsewhere, such as in .cer files, you can make them available to Chilkat in the following way:

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.XmlCertVault")

' Please review the methods available in the XML certificate vault class.  Different methods exist for adding certificates
' from various sources, such as PEM, PFX, or in-memory sources..
