Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: Once the utility has been installed, you can view the current operation modes by issuing the ccencrypt -h command.

A block of code is set as follows:

select [field(s)] from [table] where [variable] = [value]; 
update [table] set [variable] = [value]; 

Any command-line input or output is written as follows:

sudo apt install python python3 python-setuptools python3-setuptools python-pip python3-pip
sudo pip install shodan

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Now that we can decrypt the communication, we can right-click on the packet and select Follow | TLS Stream.”
