Create self signed SSL certificate

Create a self-signed SSL certificate for React JS, before starting to explore, I want to add a little bit about this

A self-signed certificate is a digital certificate that is created and signed by the same entity it identifies. Unlike certificates issued by trusted Certificate Authorities (CAs), self-signed certificates aren't verified by external parties. They're commonly used for local development, testing, or internal systems where the identity verification provided by a CA is not necessary. Although self-signed certificates can secure communication, they lack the third-party validation provided by CA-signed certificates, and users may encounter browser warnings when accessing websites using self-signed certificates.

it will done in a few steps

there are lots of ways to create a Self-signed certificate but I am using here mkcert

you can visit this URL 

https://chocolatey.org/install#individual

and download the steps to install Chocolatey, if you don't want to visit it just need to follow the steps for Windows

1. Open the PowerShell in administrator mode and execute the below script

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

once you execute it, it will download the Chocolatey, and also create the environment in your window machine

to verify, you can simply check the environmental variable from your compute property

you can also verify from the install location by opening

C:\ProgramData\chocolatey

once you verify, need to execute some other commands, in the Powershell

2. choco install mkcert

you can also ensure the mkcert is installed or not by checking the same location.

once you verify just run the 

3. mkcert -version

to check which version was installed.

now the next step is to execute

4. mkcert -install

this command installed the mkcert environment on your machine

now we are in the final step, you have to open your Visual Studio Code, solution inside the root folder of your react app, and execute the below commands

5. mkcert -key-file localhost-key.pem -cert-file localhost.pem localhost

these commands create key and certificate files in your local machine, here I am using localhost for my local development environment, you can replace it if you are using any specific domain for development

now we are very close.

the last step is to open your package.json file and add the path on the start command example

"start": "set HTTPS=true&&set SSL_CRT_FILE=

./localhost.pem&&set SSL_KEY_FILE=./localhost-key.pem

&&react-scripts start",

These commands told the system to start in https mode.

now you only need to run this

6. npm start
