checking ssl certificate with openssl

First, make sure that your Apache compiles the SSL module, which is the necessary condition to support SSL certificate (if not, compile, "open Phpstudy" "Other options Menu", "php extension", "Php-openssl" in front of the check box).Create the CERT directory under Apache's installation directory, and copy all downloade

Recently in a project, the project was previously used. NET do, now need to rewrite with PHP. After development, you need to migrate the SSL certificate on IIS to the Apache environment. Workaround: Roughly three steps First, export the certificate file to IIS 1. Start-> Run->mmc 2. Menu-> file-> Add/Remove snap-in 3. Select the

In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process.

This document, combined with the command line tool s_client provided by openssl, lists various authentication failures and provides troubleshooting methods.

A certificate in pfx format needs to be converted to the CER format at work. The original practice is to first import the pfx format certificate to the browser, and then export it from the browser, however, this is too slow for batch operations. You can use the commands provided by OpenSSL to meet this requirement. Ope
