/* Example using an in memory PEM user certificate and RSA key to retrieve an

- * if you want a properly secure connection
+ * Note that to maintain simplicity this example does not use a CA certificate
+ * for peer verification. However, some form of peer verification
+ * must be used in real circumstances when a secure connection is required.
