Worse, they suspect a possible collision in SHA1 as well.

I think we're beginning to see the possibility that entropy generation
and cryptography will never truly be secure; it's just that we can
invent complexity faster than we can explore and/or explain it, so
showstopping bugs are always lagging deployment.

I'm waiting for the first quantum crypto crack to be announced. ;)
