This example shows how to configure HTTPS certificates from Let's Encrypt across three server environments. The code demonstrates obtaining certificates via the `letsencrypt-auto` command-line tool with the `certonly --manual` flag, which requires placing a verification file on the domain. The Node.js implementation uses the `https` module with `fs.readFileSync` to load the PEM files from `/etc/letsencrypt/live/example.com/`. The Apache configuration uses `SSLCertificateFile`, `SSLCertificateKeyFile`, and `SSLCertificateChainFile` directives, while the NGINX setup relies on `ssl_certificate` and `ssl_certificate_key` directives pointing to `fullchain.pem` and `privkey.pem`.

This example demonstrates the process of setting up mutual TLS (client-side SSL) authentication for web servers. It walks through generating self-signed certificates using the OpenSSL command-line tool, including creating a Certificate Authority root, client keys, and PKCS#12 or PEM conversions for browser and application use. The guide references nginx configuration directives such as `ssl_client_certificate` and `ssl_verify_client` to request and validate client certificates, and it links to external resources for integrating with backend applications. The gist is a textual reference, not a data visualization.

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 demonstrates how to configure a Node.js HTTPS server with Server Name Indication (SNI) to serve multiple SSL certificates for different hostnames. It shows the setup for routing requests to distinct backend ports using the http-proxy library, with an SNICallback that selects the appropriate certificate context based on the incoming hostname. The code uses Node.js core `crypto.createCredentials` and `fs.readFileSync`, along with a custom `getCABundle` function that parses a bundled certificate file into an array by splitting on the `-END CERTIFICATE-` marker. It explicitly maps example-a.com and example-b.com to localhost ports 10000 and 10001.

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.

Simple Golang HTTPS/TLS Examples

This example demonstrates multiple approaches to implementing HTTPS and TLS in Go, showing both a standard HTTP server with `http.ListenAndServeTLS` and lower-level TLS connections using `crypto/tls`. It includes separate server and client implementations that communicate over TLS, with the server handling connections concurrently via goroutines. The code also shows certificate generation commands using OpenSSL and a hardened TLS configuration with specific cipher suites and minimum protocol version for achieving a perfect SSL Labs score.

This example demonstrates a multi-domain HTTP/HTTPS reverse proxy server built with Node.js and the `http-proxy` module. It routes incoming requests to distinct backend applications based on the requested hostname, with separate configurations for `www1.localhost` and `www2.localhost`. The server uses `crypto.createCredentials` for HTTPS SNI callbacks, enabling per-domain TLS certificates. Each backend app, defined in separate files like `www1_app.js`, responds with a plain-text message confirming the successful proxy and echoing request headers, illustrating how the proxy handles both HTTP and HTTPS traffic across multiple virtual hosts.

This example demonstrates a shell script that sets up a cloud-based development environment, installing code-server and configuring it with nginx as a reverse proxy. It shows the infrastructure provisioning process, including user creation, SSH key copying, and self-signed SSL certificate generation using openssl. The code uses bash commands, systemd services, and nginx configuration to enable remote access to a VS Code instance through a secure HTTPS connection, with a redirect server for the --link feature. The script relies on curl, apt, and standard Unix utilities rather than visualization libraries.

This example demonstrates a client-side verification request for a digital health certificate, sending an encrypted payload to the Ubirch API. It shows how to authenticate with mutual TLS using a local PEM certificate and key file, then posts the certificate data as JSON. The code relies on the Node.js `request` library and the `fs` module to read the credential files, with the API endpoint configured for the `api.uve.demo.ubirch.com` host. The response body, containing the verification result, is logged to the console along with any errors.
