This article provides a guide on how to generate your own TLS certificates and keys for OpenVPN connection that uses TLS authentication. This guide is aimed at Ubuntu users. Step 1: downloading Easy-Rsa edit edit source Almost all of the steps will be done through the terminal. Apr 12, 2020 In this video, we will learn how to generate a SSL/TLS certificate signing request (CSR) and have it signed by a Certificate Authority (CA). For the purpose of this demo, we won’t submit the CSR.
- Creating a TLS encryption key and certificate (If you are unfamiliar with the abbreviation “ TLS “: it is the successor to SSL.) The internet is the best invention since sliced bread but it has become an evil place more than ever.
- Jul 09, 2019 The private key gets generated along with your Certificate Signing Request (CSR). The CSR is submitted to the certificate authority right after you activate your certificate, while the private key must be kept safe and secret on your server or device. Later on, this key is used for installation of your certificate.

What is a Self-Signed TLS Certificate?

Self-signed TLS certificates are suitable for personal use or for applications that are used internally within an organization. If you intend to use your SSL certificate on a website, see our guide on enabling TLS for NGINX once you’ve completed the process outlined in this guide.
Create the Certificate
- Change to the
root
user and change to the directory in which you want to create the certificate and key pair. That location will vary depending on your needs. Here we’ll use/root/certs
: - Create the certificate:You will be prompted to add identifying information about your website or organization to the certificate. Since a self-signed certificate won’t be used publicly, this information isn’t necessary. If this certificate will be passed on to a certificate authority for signing, the information needs to be as accurate as possible.The following is a breakdown of the OpenSSL options used in this command. There are many other options available, but these will create a basic certificate which will be good for a year. For more information, see
man openssl
in your terminal.-newkey rsa:4096
: Create a 4096 bit RSA key for use with the certificate.RSA 2048
is the default on more recent versions of OpenSSL but to be sure of the key size, you should specify it during creation.-x509
: Create a self-signed certificate.-sha256
: Generate the certificate request using 265-bit SHA (Secure Hash Algorithm).-days
: Determines the length of time in days that the certificate is being issued for. For a self-signed certificate, this value can be increased as necessary.-nodes
: Create a certificate that does not require a passphrase. If this option is excluded, you will be required to enter the passphrase in the console each time the application using it is restarted.
Here is an example of the output: - Restrict the key’s permissions so that only
root
can access it: - Back up your certificate and key to external storage. This is an important step. Do not skip it!
