-- | -- <<images/hawk-logo.png>> -- -- __Hawk__ is a HTTP authentication scheme using a hash-based message -- authentication code (HMAC) algorithm to provide partial HTTP -- request cryptographic verification. -- -- The message verification covers HTTP method, request URI, host, and -- optionally the request payload of both requests and responses. -- -- Similar to the HTTP [Digest access authentication -- schemes](http://www.ietf.org/rfc/rfc2617.txt), /Hawk/ uses a set of -- client credentials which include an identifier (e.g. username) and -- key (e.g. password). -- -- Likewise, just as with the Digest scheme, the key is never included -- in authenticated requests. Instead, it is used to calculate a -- request MAC value which is included in its place. -- -- Unlike Digest, this scheme is not intended to protect the key -- itself (the password in Digest) because the client and server must -- both have access to the key material in the clear. -- -- The /Hawk/ scheme requires the establishment of a shared symmetric -- key between the client and the server, which is beyond the scope of -- this module. Typically, the shared credentials are established via -- an initial TLS-protected phase or derived from some other shared -- confidential information available to both the client and the -- server. -- -- More information about /Hawk's/ design can be found at its web -- site: https://github.com/hueniverse/hawk -- -- == Usage -- -- To use /Hawk/, depending on your application, use a qualified -- import of either "Network.Hawk.Server" or "Network.Hawk.Client". -- -- These modules respectively contain functions to generate -- @Server-Authorization@/@Authorization@ headers, as well as -- functions to authenticate requests/responses from the -- client/server. -- -- Additionally, there is a small example server and client in the -- <https://github.com/rvl/hsoz project git repository>. module Network.Hawk ( module Network.Hawk.Types ) where import Network.Hawk.Client import Network.Hawk.Server import Network.Hawk.Types
