Overview of this book

Jupyter has garnered a strong interest in the data science community of late, as it makes common data processing and analysis tasks much simpler. This book is for data science professionals who want to master various tasks related to Jupyter to create efficient, easy-to-share, scientific applications. The book starts with recipes on installing and running the Jupyter Notebook system on various platforms and configuring the various packages that can be used with it. You will then see how you can implement different programming languages and frameworks, such as Python, R, Julia, JavaScript, Scala, and Spark on your Jupyter Notebook. This book contains intuitive recipes on building interactive widgets to manipulate and visualize data in real time, sharing your code, creating a multi-user environment, and organizing your notebook. You will then get hands-on experience with Jupyter Labs, microservices, and deploying them on the web. By the end of this book, you will have taken your knowledge of Jupyter to the next level to perform all key tasks associated with it.

Using SSL

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.

How to do it...

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.

Creating an SSL certificate

You can create a certificate using openssl with this command:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout mykey.key -out mycert.pem

Where 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 key
rsa:2048: Use the 2,048-bit RSA algorithm
-keyout: Location to place the key
-out: Location to place the certificate

Apply the SSL certificate

You can set the SSL certificate to be used by...
