Hello, thank you for your excellent book.
But I am out of ressources in chapter 8, my S3 region is in eu-central-1, and it requests a V4 signature.

It is a very complex thing, which I cannot get right actually, could you provide a V4 version in a next iteration of the book ?

Thank you again.

The code of the R package aws.signature has valuable snippets too.
