Marc Stevens (https://marc-stevens.nl/research/, CWI, Amsterdam, NL) is
working on SHA-1 collisions. He has yet to generate one, but as I
understand it, the only thing lacking right now is enough computing power.
Generating such a collision is significant from a practitioner viewpoint.
Without a concrete example, tales of weaknesses in SHA-1 will be brushed
off as 'merely theoretical'. The hashclash project
(https://www.win.tue.nl/hashclash/), for example, was instrumental in
convincing people to stop using MD5. Incidentally, Marc was involved in
that project as well.
