Configure localhost with secure https

 

Steps :

sudo apt install libnss3-tools -y 

wget https://github.com/FiloSottile/mkcert/releases/download/v1.4.3/mkcert-v1.4.3-linux-amd64 

sudo cp mkcert-v1.4.3-linux-amd64 /usr/local/bin/mkcert 

sudo chmod +x /usr/local/bin/mkcert 

mkcert -install

Now use your virtualhost name in the below command instead of app.localhost. You can generate same certificate for multiple virtualhosts. Add multiple virtualhosts space separated in the below command.

mkcert app.localhost localhost 127.0.0.1 

Use certificates in Apache ssl config, and restart Apache. Now open localhost and other virtualhosts in the browser. it should be secured.
