Along the same lines, if you were to determine that the contents of your Notebook are valuable, you may want to use SSL to encrypt all transmissions between your Notebook. At a minimum, then, any authentication information will be encrypted as well and this will prevent hijacking.
A well-known service for providing free SSL certificates is Let's Encrypt (https://letsencrypt.org/). Let's take a look at how to create and apply an SSL certificate in the following sections.
You can create a certificate using openssl with this command:
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout mykey.key -out mycert.pemWhere the several options specified are as follows:
-x509: We are using x509 protocol-days 365: Good for one year-newkey: We are generating a new keyrsa:2048: Use the 2,048-bit RSA algorithm-keyout: Location to place the key-out: Location to place the certificate
