So here is a step-by-step setup guide of generating and installing a SSL certificate for Elastic Load Balancer (ELB) in AWS.
With the increasing popularity as well as the need for the SEO, SSL certificates are now becoming a prerequisite for any website that considers the security of the visitors as serious thing. But just purchasing an SSL certificate doesn’t make your website safe and it needs to be installed properly on the AWS server to make it work so as to actually benefit from it. You can seek the assistance of a server management expert like us to get the SSL certificate installed in your AWS server.

Uploading GoDaddy SSL certificate on AWS Load Balancer
So you have purchased an SSL certificate from GoDaddy and now you want to deploy it on the Amazon Load Balancer.
In the AWS web console, go the “Load Balancers” section. Select your ELB and click on the “Listeners” tab. Now add a new listener for HTTPS
Click on the “Change” link the “SSL Certificate” column. You will see the following screen.
Certificate Name: Enter the name you want to give this certificate.
Private Key: This private key is the one you generated when generating the CSR and it is called server.key. This file will now have to be altered to create an Amazon supported private key. This can be done using openssl as follows.
openssl rsa -in server.key -out decrypted-server-key.pem
Now copy the contents of the file decrypted-server-key.pem and paste them into the “Private Key” section.
Public Key Certificate: This is the file that you got from GoDaddy, it would look something like “yourdomain.crt”.
Copy the entire lines and paste it into the “Public Key Certificate” section.
That’s it. Click on “Save” and you are done.
