Hackage security library.
The hackage security library provides both server and client utilities for securing the Hackage package server (https://hackage.haskell.org/). It is based on The Update Framework (https://theupdateframework.com/), a set of recommendations developed by security researchers at various universities in the US as well as developers on the Tor project (https://www.torproject.org/).
The current implementation supports only index signing, thereby enabling untrusted mirrors. It does not yet provide facilities for author package signing.
The library has two main entry points: Hackage.Security.Client is the main entry point for clients (the typical example being cabal), and Hackage.Security.Server is the main entry point for servers (the typical example being hackage-server).
