In Part 3 of this blog, we demonstrated how you can generate and consume pre-signed URLs using SSE-S3. In this blog, I will provide code examples to show how you can generate and consume pre-signed URLs using one of the more advanced options, namely SSE-C (server-side encryption with customer-provided encryption keys). The code samples assume the […]

Private content can be served through Amazon CloudFront in two ways: through signed URLs or signed cookies. For information about which approach to choose, see Choosing Between Signed URLs and Signed Cookies. The AWS SDK for .NET includes an Amazon.CloudFront.AmazonCloudFrontUrlSigner utility class that can be used to generate signed URLs. Based on a customer request, […]

As mentioned in Part 1 and Part 2 of this blog, there are fundamentally four ways you can generate Amazon S3 pre-signed URLs using server-side encryption (SSE). We demonstrated how you could do so with SSE-KMS (server-side encryption with AWS Key Management Service). In this blog, I will provide further sample code that shows how […]

The AWS Tools for Windows PowerShell have until now been made available in a single MSI installer that also contains the AWS SDK for .NET and AWS Toolkit for Visual Studio. MSIs have historically been the primary method of installing software on Windows. On the Linux and OS X platforms, package managers have become the […]

One of the most powerful tools for accessing Amazon DynamoDB is the use of a DynamoDB domain-specific language (DSL) called expressions. If you look closely, you will find the support of DynamoDB expressions everywhere. For instance, you can access the attributes of an item using projection expressions. You can query or scan items using filter […]

To continue from the previous blog, I will provide specific code examples that show how you can generate and consume pre-signed URLs using server-side encryption with AWS Key Management Service (SSE-KMS). A pre-requisite to this option is that you must be using Signature Version 4 (SigV4). You can enable SigV4 in the AWS SDK for […]

Today, we pushed our new modularized version of the AWS SDK for .NET to NuGet in preview. This means there are separate NuGet packages for each AWS service. For example, if your application uses Amazon S3 and Amazon DynamoDB, then instead of including the existing AWSSDK package that includes all the AWS services, you can […]

By default, all objects and buckets are private in Amazon S3. Pre-Signed URLs are a popular way to let your users or customers upload or download specific objects to/from your bucket, but without requiring them to have AWS security credentials or permissions. In part 1 of this blog, we will take a look at all […]

Today, we are introducing a new addition to the AWS toolkit for Eclipse — the AWS OpsWorks plugin. This new plugin allows you to easily deploy your Java web applications from your development environment directly to AWS infrastructures. So you might remember the AWS CodeDeploy plugin that we introduced recently, and some of you have […]

Our earlier blog post introduced authentication with Amazon Cognito in the browser. Amazon Cognito has since simplified the authentication workflow. This article describes authenticating the SDK in the browser using Amazon Cognito and supported public identity providers like Google, Facebook, and Amazon. Step 1 and Step 2 outline registering your application with a public identity […]
