 The Hackage security library provides both server and client utilities
 for securing the Hackage package server. It is based on The Update
 Framework, a set of recommendations developed by security researchers
 at various universities in the US as well as developers on the Tor
 project.
 .
 The current implementation supports only index signing,
 thereby enabling untrusted mirrors. It does not yet provide
 facilities for author package signing.

 This package provides a library for the Haskell programming language.
