How to Install Free Lets Encrypt SSL in Namecheap Shared Hosting 2021




I have been using the PHP client from Kelunik earlier for Let’s Encrypt SSL till last month. I noticed that the Acme API now has version 2, and version 1 will be deprecated from June 2021. So, I had to upgrade the API version but found it challenging and complicated to switch between the APIs. Finally, I deleted the PHP client and switched to a simple SSH from Sinclair named Became.

The Github repo of Kelunik says that it is compatible with the V2 API of Acme, but I thought that I would have to make a fresh install, and I could not upgrade. If you’re interested in the PHP client, you can look at my old blog post here.

So, log in to your web hosting using shell access and follow the instructions below-

  1. Clone the script into your hosting folder
    git clone
  2. Then go inside the cloned folder. We will run all of our operations there
    cd bacme/
  3. Now, we will run the script and add the necessary variables for it to issue a new certificate
    ./bacme -e {youremail address here} -w {your home directory} {your domain}
  4. Upon successful completion of the certificate generation, you will see something like this

5. Now you can find the certificate and the key files inside /bacme/domainName/ folder

Now, you need to copy the text inside the .crt file and .key file and paste inside the SSL Management System in your cPanel.

And you’re done!
