All necessary steps are executed by a single OpenSSL invocation: from private key generation up to the self-signed certificate. Remark #1: Crypto parameters Since the certificate is self-signed and needs to be accepted by users manually, it doesn't make sense to use a short expiration or weak cryptography.

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.

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!
