RGW assumes unauthenticated requests are sent by an anonymous +user.

Replace ``{hash-of-header-and-secret}`` with +a hash of the header string and the secret corresponding to the access key ID. + +To generate the hash of the header string and secret, you must: + +#. Get the value of the header string. +#. Normalize the request header string into canonical form. +#. Generate an HMAC using a SHA-1 hashing algorithm. + See `RFC 2104`_ and `HMAC`_ for details. +#. Encode the ``hmac`` result as base-64. + +To normalize the header into canonical form: + +#. Get all fields beginning with ``x-amz-``. +#. Ensure that the fields are all lowercase. +#. Sort the fields lexicographically. +#. Combine multiple instances of the same field name into a + single field and separate the field values with a comma. +#. Replace white space and line breaks in field values with a single space. +#. Remove white space before and after colons. +#. Append a new line after each field. +#. Merge the fields back into the header. + +Replace the ``{hash-of-header-and-secret}`` with the base-64 encoded HMAC string. + +Authentication against OpenStack Keystone +----------------------------------------- + +In a radosgw instance that is configured with authentication against +OpenStack Keystone, it is possible to use Keystone as an authoritative +source for S3 API authentication. To do so, you must set: + +* the ``rgw keystone`` configuration options explained in :doc:`../keystone`, +* ``rgw s3 auth use keystone = true``. + +In addition, a user wishing to use the S3 API must obtain an AWS-style +access key and secret key.
