Generating a Private Key

The third step is generating a private key. A private key needs to be created using the following command.
openssl genpkey -algorithm RSA -out example.com.key
In this command, replace example.com.key with the name of your key.
When executing the command, you will be prompted to enter a password for the private key. This password will be used every time you access the private key, so make sure it is securely stored.

Creating a Self-Signed Certificate

It is necessary to create a self-signed certificate using the generated private key: openssl req -x509 -new -key example.com.key -out example.com.crt
After executing this command, OpenSSL will ask you to enter information about the certificate. The necessary information may include: country, province, city, etc. This information will be included in the self-signed certificate.
