About

An open-source project (MIT license) that targets and complements AWS Signature Version 4 for API requests. It aims to provide a good developer experience by making it simple to generate AWS4-HMAC-SHA256 HTTP Authorization header.

Your versatile AWS Signature Version 4 companion for modern development with .NET 9 and .NET 10.

It is, by heart, free, flexible and built to extend and boost your agile codebelt.

Codebelt.Extensions.AwsSignature4 for .NET

The Codebelt.Extensions.AwsSignature4 namespace complements the Cuemon.AspNetCore.Authentication namespace while providing a way making and signing HTTP requests in the context of specific AWS services using Signature Version 4.

More documentation available at our documentation site:

CSharp Example

In this example we create an HTTP request with an AWS Signature Version 4 header. The example used here is part of the unit test for Aws4HmacAuthorizationHeaderBuilder. Unit test is based on xUnit API and is written using convenient extensions for xUnit API by Codebelt.

using var test = WebHostTestFactory.Create(); 
var context = test.Host.Services.GetRequiredService<IHttpContextAccessor>().HttpContext; 

var timestamp = DateTime.Parse("2022-07-10T12:50:42.2737531Z"); // <-- change this to valid date/time

context.Request.Headers.Add(HttpHeaderNames.Host, "cuemon.s3.amazonaws.com");
context.Request.Headers.Add("x-amz-date", timestamp.ToAwsDateTimeString());
context.Request.Headers.Add("x-amz-content-sha256", UnkeyedHashFactory.CreateCryptoSha256().ComputeHash("").ToHexadecimalString());
context.Request.QueryString = QueryString.Create("list-type", "2");

var headerBuilder = new Aws4HmacAuthorizationHeaderBuilder()
 .AddFromRequest(context.Request)
 .AddClientId("AKIAIOSFODNN7EXAMPLE") // <-- change this to valid access key
 .AddClientSecret("wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY") // <-- change this to valid secret
 .AddCredentialScope(timestamp);

var header = headerBuilder.Build().ToString(); // <-- AWS4-HMAC-SHA256 Credential=AKIAIOSFODNN7EXAMPLE/20220710/eu-west-1/s3/aws4_request, SignedHeaders=host;x-amz-content-sha256;x-amz-date, Signature=3d2c4a14b38d0283bb697176ade57b2118110de0f00c387d7f0ef58c55a5b91d
