Hi,

the "Hash: SHA256" is coming from the GPG signature, it's unrelated to the
checksum of the sha1/sha256/md5sum (files).
There's nothing wrong in the setup, though it's unfortunate that GPG is adding
this Hash message, but AFAICS there's nothing we can do about it. Just don't let
yourself get confused by it. :)

regards,

Hello!
I downloaded the ISO grml96-full_2014.11.iso from the torrent I got
here: https://grml.org/download/
(http://download.grml.org/grml96-full_2014.11.iso.torrent), and then
check the hash with the one found here:
http://download.grml.org/grml96-full_2014.11.iso.sha1.asc

-----BEGIN PGP SIGNED MESSAGE-----

Hash: SHA256

First I checked the signature, which was OK. Then I run sha256sum on my
file and got:

hackan@hc-vision-black:/mnt/Downloads/Downloads/0Utils/Linux/grml$ sha256sum grml96-full_2014.11.iso

d3330229a69f52ec00d6023fa3241bb43a29f5ebb29c7e518cdb3585ee9a0cae  grml96-full_2014.11.iso


which is different! this is either really bad or just a small mistake.
what happened?

EDIT:
crap, just as i was writing this, i realised that it was a SHA1 hash,
not a SHA256 one as the file says:

hackan@hc-vision-black:/mnt/Downloads/Downloads/0Utils/Linux/grml$ sha1sum grml96-full_2014.11.iso

ea7204ed77fa3df3a4ed68e3b8e2ad6f95d5242d  grml96-full_2014.11.iso


which is fine. however, the file should read Hash: SHA1 instead of SHA256
