InvalidCypherTextException when reading an encrypted DynamoDB table which has been restored from a backup

If you attempt to read encrypted data from a DynamoDB table which has been restored from a backup to a DynamoDB table which doesn’t match the original table name, you may see the following errors:

Enabling HTTPS on Elastic Beanstalk without a load balancer

By Matt Button |  Aug 6, 2018  | aws, alb, elastic-beanstalk, https, prototype

The recommended way to enable HTTPS in Elastic Beanstalk is to use one of AWS’s load balancers such as the Application Load Balancer (ALB) which supports autoscaling, fault tolerance, and other things.

This blog is about hosting a web app prototype on a single EC2 instance, using HTTPS via Let’s Encrypt, without a load balancer.

Using an AWS ALB costs a minimum of about $18 per month, on top of any other charges you currently have, such as $5 for the t2.micro instance that you may be running your prototype on.

So, if you’ve only got one EC2 instance in Elastic Beanstalk for your prototype, and don’t currently want the benefits of an ALB (fault tolerance, auto-scaling, etc), but do want the benefits of HTTPS (protection from interception, man-in-the-middle (MITM) attacks, etc), read on.

How I host and update www.mattbutton.com on AWS with CloudFlare and Amazon S3 Static Website Hosting

I’ve been hosting this blog on Amazon S3 for a few months now, and thought it would be a good idea to write about how it’s set up, in case future me needs to refer to it, and to give pointers to anybody else who is interested in setting up their own website using Amazon S3, HTTPS, and the CloudFlare CDN.

Hosting this website costs cents per month, and avoids security risks of other blog platforms such as Wordpress by being purely static, consisting just regular HTML files, JavaScript, and images; which means no PHP, .NET, etc. This works well with what I need in a blog.
