Provide AWS{3,4}Signer that takes a HttpRequestMessage

[paddie]

Or is there some example of how to convert a HttpRequestMessage to an IRequest that the current AWS4Signer uses.

We're calling api-gateway using IAM authorization which requires the execute-api service, and that requires the AWS4Signature that uses HMAC-256. It would be really nice to have some maintained utility that enables one to sign a generic HttpRequestMessage.

I've copied this gist for now, but I am seeing some discrepancies between what is in the aws-sdk-net AWS4Signer.

Is there a better way than the one I am using?

We don't have a better approach now but making a signing code more accessible is something we want to do for these API Gateway cases.

[paddie]

Aye, that sounds good. I'm merging what is in the aws4signer and the gist
for now (since it is missing some steps), let me know if you want to look
at it. The signer will take only a HttpRequstMessage and add the Authorize
headers as your signer does.

This has been added to our feature request list: https://github.com/aws/aws-sdk-net/blob/master/FEATURE_REQUESTS.md

I'm using AWS Elastic Search Service and requests need to be signed.

There is a nuget package which has to implement the signing code but there's bugs in that library.

For example if you try to enable gzip compression it doesn't work and you get the error:

The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

Is gzip compression compatible with v4 signing?

Any update on when signer would be available as a utility in sdk?

[NeilBostrom]

Just leaving a +1 for having public API for signing HttpClient requests (or anything really) and not having to use internal namespaces for it. My use case is querying an AppSync GraphQL API protected by V4 signing.

Having the ability to sign requests for AWS services should be considered a high priority for a production AWS SDK!

We just ran into a big roadblock here because I decided to use signed API GATEWAY for a project and one of our backend systems is in .NET and well, oof :/

The SDK not enabling authenticating IAM against API Gateways is currently being a blocker.
