SSL Complete Guide 2021: HTTP to HTTPS - Generate a Self-Signed Certificate Using OpenSSL

The video tutorial covers the process of managing SSL certificates on a web server using OpenSSL. It begins with checking the OpenSSL installation, deleting old certificates, and troubleshooting NGINX errors. The tutorial then guides through creating a self-signed certificate, configuring NGINX with a passphrase, and testing the setup to ensure the server runs correctly with the new certificate.

What tool is used to manage SSL certificates in Ubuntu?

• Nginx

• Apache

• Docker

• OpenSSL

What is the first step in managing SSL certificates as mentioned in the tutorial?

• Creating a new certificate

• Deleting old certificates

• Checking OpenSSL installation

• Restarting the server

Why did the NGINX server fail to restart initially?

• Missing certificate files

• Incorrect server configuration

• Network issues

• Outdated software

What type of certificate is created using OpenSSL in the tutorial?

• Extended validation certificate

• Domain-validated certificate

• Self-signed certificate

• Wildcard certificate

What is the purpose of the PEM passphrase in the context of SSL certificates?

• To encrypt the certificate

• To secure the private key

• To authenticate the user

• To validate the server

What issue arises when using a self-signed certificate in a web browser?

• It requires special software

• It is too expensive

• It expires too quickly

• The browser does not trust it

What parameter is used in NGINX to specify the path to the passphrase file?

• ssl_certificate

• ssl_password_file

• ssl_key

• ssl_passphrase

What was the final step to ensure the NGINX server ran correctly?

• Changing the server port

• Reinstalling NGINX

• Adding a semicolon in the configuration

• Removing the passphrase

What is the expected outcome when accessing a website with a self-signed certificate?

• The website loads without errors

• The browser shows a security warning

• The certificate is automatically trusted

• The website is blocked

What is the main reason for using a self-signed certificate in the tutorial?
