Sets the UseSecureString property.
            By default, the AWS Secret Access Key is stored
            in a SecureString (true) - this is one of the secure
            ways to store a secret provided by the .NET Framework.
            But, the use of SecureStrings is not supported in Medium
            Trust Windows Hosting environments. If you are building an
            ASP.NET application that needs to run with Medium Trust,
            set this property to false, and the client will
            not save your AWS Secret Key in a secure string. Changing
            the default to false can result in the Secret Key being
            vulnerable; please use this property judiciously.
