http: introduce AWS HTTP v4 Signature It is a security process for HTTP. It doesn't seems to be standard, but it is used by some cloud providers. Aws: https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html Outscale: https://wiki.outscale.net/display/EN/Creating+a+Canonical+Request GCP (I didn't test that this code work with GCP though): https://cloud.google.com/storage/docs/access-control/signing-urls-manually most of the code is in lib/http_v4_signature.c Information require by the algorithm: - The URL - Current time - some prefix that are append to some of the signature parameters. The data extracted from the URL are: the URI, the region, the host and the API type example: https://api.eu-west-2.outscale.com/api/latest/ReadNets ~~~ ~~~~~~~~ ~~~~~~~~~~~~~~~~~~~ ^ ^ ^ / \ URI API type region Small description of the algorithm: - make canonical header using content type, the host, and the date - hash the post data - make canonical_request using custom request, the URI, the get data, the canonical header, the signed header and post data hash - hash canonical_request - make str_to_sign using one of the prefix pass in parameter, the date, the credential scope and the canonical_request hash - compute hmac from date, using secret key as key. - compute hmac from region, using above hmac as key - compute hmac from api_type, using above hmac as key - compute hmac from request_type, using above hmac as key - compute hmac from str_to_sign using above hmac as key - create Authorization header using above hmac, prefix pass in parameter, the date, and above hash Signed-off-by: Matthias Gatto <matthias.gatto@outscale.com> Closes #5703
