# Basic Auth

data BasicAuthResult usr #

servant-server's current implementation of basic authentication is not immune to certain kinds of timing attacks. Decoding payloads does not take a fixed amount of time.

The result of authentication/authorization

mkBAChallengerHdr :: ByteString -> Header #

Internal method to make a basic-auth challenge

decodeBAHdr :: Request -> Maybe BasicAuthData #

Find and decode an `Authorization` header from the request as Basic Auth

runBasicAuth :: Request -> ByteString -> BasicAuthCheck usr -> DelayedIO usr #

Run and check basic authentication, returning the appropriate http error per the spec.
