This example shows a shell script that automates the creation of self-signed SSL certificates and keys without interactive prompts. It generates a random passphrase using `openssl rand`, creates a private key with `openssl genrsa`, and produces a certificate signing request via `openssl req` with a hardcoded subject. The script strips the passphrase from the key using `openssl rsa`, then signs the certificate with `openssl x509` for a 36500-day validity. The final `server.crt` and `server.key` files are renamed to `ssl.crt` and `ssl.key`.

generating SSL keys and Certificate Signing Requests for Heroku / Nginx / RapidSSL

This example shows a step-by-step terminal transcript of generating an SSL key and certificate signing request, then unlocking, combining, and uploading the certificate to Heroku. The process uses the OpenSSL command-line API (`openssl genrsa`, `openssl req`, `openssl rsa`, `cat` for concatenation) and Heroku’s CLI (`heroku ssl:add`, `heroku addons:add`). The text-based log traces the flow from key creation through DNS activation, with shell prompts and command outputs as the visual data.

Use https certificate on localhost with Express

This example shows how to run an Express web server over HTTPS on localhost, delivering a plain-text response. It creates a Node.js application that reads SSL certificate files (`localhost-key.pem` and `localhost.pem`) generated by the mkcert utility, then uses the `https.createServer` method with those credentials. The Express app defines a single route for the root path, and the server listens on port 3001. The code demonstrates the required setup steps, including installing mkcert and generating a trusted local certificate.

This example shows a Bash script that automates the setup of a Linux scavenger-hunt lab environment, from downloading a deploy key to provisioning a virtual machine. The script uses `curl` to fetch an SSH private key, `git clone` and `git submodule update --init --recursive` to retrieve the lab definitions, and `vagrant up` to launch the machine. It then parses `vagrant ssh-config` output with `grep`, `awk`, and `sed` to extract the hostname and port, printing SSH connection instructions for the student user.

This example shows a shell script that automates the setup of a Linux scavenger hunt lab environment by downloading a deploy key, cloning a GitLab repository, and running Vagrant to provision the machine. The script uses `curl` to fetch an SSH key, `git clone` with submodules to pull the lab definitions, and `vagrant up` to launch the virtual machine. It then extracts the SSH hostname and port from `vagrant ssh-config` using `grep` and `awk`, printing connection instructions for the student user.

sudo for a command without a password prompt.

This example demonstrates how to configure a Linux system so that a specific user can run sudo commands without being prompted for a password. It shows the contents of a shell script that opens the sudoers file with `visudo` and adds a line granting the user `prash` the `NOPASSWD` privilege for all commands on all hosts. The script relies on the `visudo` command-line tool to edit the file safely, ensuring syntax validation before saving. No external data sources or rendering libraries are used; the visualization is a direct text display of the configuration steps.

How to create a CSR for the identity service

This example generates a certificate signing request (CSR) for an identity service using an Ed25519 key pair. It demonstrates how to construct a public key with validity dates and a hardware device ID, then output the key as a string. The code uses `GeneratorKeyFactory.getPrivKey` to decode and load the private key from a Base64 string, and `PublicKeyCreationHelpers.getPublicKey2` to build the key with the specified curve, timestamps, and device identifier. The result is printed via `println` after handling success or failure through a `toTry` match.

This visualization demonstrates the process of generating and displaying an SSH key, showing step-by-step terminal commands and their outputs. The code uses vanilla JavaScript and HTML/CSS to render a structured guide with command examples, including `ssh-keygen` variations and `cat` commands for viewing public keys. It presents the data as a static, text-based instructional card, with syntax highlighting applied to differentiate commands from comments and output. The interface relies on simple DOM manipulation and CSS styling rather than charting or mapping libraries.

This example uses a shell script to compile and install OpenSSH 7.3p1 from source on Ubuntu 16.04. It downloads the portable release tarball from OpenBSD’s CDN, extracts it, and builds the software using `./configure`, `make`, and `checkinstall`. The script’s annotations and inline comments document each step, referencing the original Ask Ubuntu guide for adaptation. The code relies on system package managers (`apt`) and standard build tools (`gcc`, `make`, `autoconf`) rather than any visualization libraries or data APIs.
