Is there a .NET library that can sign a request with AWS V4 Signature?

Question

I have an API Gateway where I\'m setting the authentication to use AWS_IAM. This requires that I sign each request with the AWS V4 signature and attach the HMAC in the head

Answer 1

An alternative to Aws4RequestSigner is AwsSignatureVersion4. I think its API is easier to work with, but I am biased since I am the author of the latter.
