Great! > I can write up a patch for it, but I'm not sure how to get it accepted > upstream. Well, we can apply it locally first, of course. But I’m sure that the original authors will be happy to receive it via https://github.com/vincenthz/hs-cryptohash/issues Greetings, Joachim -- Joachim "nomeata" Breitner Debian Developer nome...@debian.org | ICQ# 74513189 | GPG-Keyid: F0FBF51F JID: nome...@joachim-breitner.de | http://people.debian.org/~nomeata
