This guide explains what mkcert is, its key features, and provides step‑by‑step instructions for installing the tool, generating trusted local SSL/TLS certificates for multiple domains and IPs, and configuring Nginx to enable HTTPS in a local development environment across Windows, macOS, and Linux.
This guide shows how to generate a self‑signed SSL certificate for an internal IP address using OpenSSL, configure Nginx to serve HTTPS without security warnings, and import the certificate into Chrome with the necessary extensions to avoid common name errors.
This article explains how to protect MySQL connections by using SSL/TLS, various password authentication plugins, digital signatures, and client/server certificate verification to prevent impersonation, password leakage, and data tampering.
This article introduces the open‑source mkcert tool for effortlessly creating locally trusted SSL/TLS certificates, provides step‑by‑step installation and usage commands for multiple platforms, shows how to configure Nginx with the generated files, and then promotes related AI and ChatGPT community offers and paid resources.
This article provides a step‑by‑step guide to configuring Nginx for both HTTP and HTTPS, including how to set up separate proxy passes for multiple APIs, define URL rewrite rules, configure SSL certificates, and customize error page handling using concrete configuration examples.
This article explains why Nginx reverse‑proxying to an HTTPS upstream can return a 502 Bad Gateway error when SNI is not sent, shows the relevant SSL handshake log, and provides a complete configuration example—including enabling proxy_ssl_server_name—to fix the issue and avoid reload‑related socket problems.
Learn how to install and configure the visual Nginx management tool nginx‑proxy‑manager using Docker, set up static and dynamic proxy hosts, enable automatic SSL, and integrate it with a SpringBoot‑Vue e‑commerce project, complete with step‑by‑step commands and screenshots.
This guide walks you through four progressive stages—basic configuration, SSL encryption, SCRAM authentication, and combined SSL+SASL—showing how to harden Kafka with certificates, keystores, and client settings to achieve financial‑level protection.
This tutorial walks through installing acme.sh, configuring JD Cloud DNS API credentials, issuing and installing SSL certificates for Nginx (or Docker‑based Nginx), and setting up automatic 60‑day renewal, providing all necessary commands and configuration examples.
This guide explains common certificate formats (PEM, DER, CRT, CER), shows how to generate a CA key, CSR, and signed certificate with OpenSSL, demonstrates format conversions, and provides commands for inspecting and verifying certificates, all essential for secure operations.
SSL/TLS certificates secure data between browsers and servers, but while one‑way authentication verifies only the server, mutual (two‑way) authentication also validates the client using personal authentication certificates, requiring additional keys and CA roots, making it ideal for high‑security enterprise environments.
This article introduces the open‑source tool mkcert, explains its key features, provides step‑by‑step installation and certificate generation commands, shows how to configure Nginx for HTTPS, and includes promotional notes about related community resources.
Enterprises should follow a six‑phase plan—inventorying domains, securing and installing SSL certificates, configuring servers, redirecting traffic, updating links and sitemaps, testing, and finally enforcing HTTPS‑only access—while monitoring performance impacts such as latency, bandwidth, CPU load, and handshake overhead.
This article presents a Python script that retrieves a domain's SSL certificate information, parses its start and expiration dates, converts them to datetime objects, and calculates the remaining days until the certificate expires, providing a simple command‑line tool for monitoring certificate validity.
This article introduces the open‑source tool mkcert, explains its features, shows how to install it on various operating systems, generate multi‑domain certificates, and configure Nginx for HTTPS, while also noting additional community resources and promotional offers.
This guide explains how to prepare the environment, install required Python libraries, and use a complete script that connects to a remote server via SSH to check SSL certificate expiration dates and send email alerts when certificates are near expiry.
This guide explains what ServBay Local CA is, how to locate it using macOS Keychain Access, and provides step‑by‑step instructions for reinstalling or deleting the certificate to resolve HTTPS errors during local development.
This article explains the fundamentals of the HTTP protocol, illustrates its vulnerability to man‑in‑the‑middle attacks, demonstrates why plain HTTP is insecure, and shows how HTTPS, TLS/SSL, asymmetric encryption, and certificate authorities together protect communications from interception and tampering.
This guide explains how to switch the embedded web server in Spring Boot 3.2.5, disable it, customize ports (including random and range ports), enable HTTP compression, configure SSL and HTTP/2, add servlets, filters, listeners, set up logging, and fine‑tune Tomcat and Undertow settings, all with practical code examples.
This article explains the fundamentals of the HTTP protocol, illustrates its susceptibility to man‑in‑the‑middle attacks, discusses symmetric and asymmetric encryption attempts, and then details how HTTPS (TLS) and the CA trust model protect data transmission from interception and tampering.
