Many users believe that once they’ve installed an SSL certificate on a web server, they can’t back up or export the certificate and install it on another server. Well guess what? They’re wrong. You absolutely can export a certificate with its private key.
Whether you’re migrating your server, just want to take back up of your certificate or want to export an SSL certificate because it’s corrupted, you can export or back up your SSL/TLS certificate no matter what web server you’re using.
So, when you export an SSL certificate, its private key is copied to an encrypted file on the local server. In this post, we’ll learn easy-to-implement steps for various software vendors and versions, including Microsoft IIS, Apache, and Tomcat.
