Demonstrates how to do REST Basic authentication using secure strings.

This example requires Chilkat v9.5.0.71 or greater.

Dim success As Boolean

' that contains this:

' }

Dim ssPassword As New Chilkat.SecureString

' Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
' a randomly generated session key.)
