PHP: AWS Signature 4 - How to use IAM based API

[Thor]

So banging my head a bit here I am trying to use an API that requires signature4 so from my understanding I need to
hash_hmac parameters and headers and access keys and then build up the headers.

I tried the AWS SDK and it's a disaster of bloat, any tips or places you can send me, perhaps someone has a lightweight library they built?

In need of a lifeline here...

I cannot imagine it being this complicated to call an AWS API so I am obviously missing something.

Try a read through these python examples, it may give you another outlook on the process and where you may have gone wrong..

I assume you are getting invalid signature errors when you make your request..?

More a case of I cannot find a way to build this request it seems like a metric ton of work to build a simple token for AWS, I mean what happened to the days where we used a username and password and got back a token.

AWS sigv4 is probably one of the top 3 most difficult to wrap your head around, but once you get there it is a piece of cake..

Must you absolutely use sigv4..?

This what you looking for: https://github.com/aws/aws-sdk-php/blob/master/src/Signature/SignatureV4.php ?

Just use the SDK. It is simple and does all the cruft for you, and is why it partially exists
