This module contains the V4 Authorization header AWS signature algorithm.

val sign_request : 
  access_key:string ->
  secret_key:string ->
  service:string ->
  region:string ->
  Request.t ->
  Request.t

Given a service, region, and request, produce a new request with an Authorization header constructed according to the V4 Signing algorithm. This code is a direct translation of the reference implementation from python provided at:

http://docs.aws.amazon.com/general/latest/gr/sigv4-signed-request-examples.html

Note: This requires AWS_ACCESS_KEY and AWS_SECRET_KEY environment variables to be set.

Also: Your system time must be accurate. If you are getting invalid authorization errors, check your system time!
