Configure HTTP Basic Authentication with SecureString

See more REST Examples

Demonstrates Rest.SetAuthBasicSecure, which configures HTTP Basic authentication using SecureString objects instead of plaintext strings.

Background. A SecureString keeps sensitive values encrypted in memory, reducing the window in which credentials appear as readable plaintext. This is otherwise equivalent to SetAuthBasic.

#  Normally you would not hard-code secrets in source.  You should instead obtain them from an
