SFTP use Cert's Private Key for Authentication (Windows)

See more SFTP Examples

Demonstrates how to use the private key of a pre-installed certificate (on Windows) for SFTP authentication. The certificate's private key must be marked as "exportable" when originally installed. Visual Basic 6.0

Dim success As Long
