SHA- collision found

After modified version have been broken in the past, this time around 
it's The Real Thing: https://shattered.it/

What's nice is that the attack vectors can be detected and a "hardened" 
version of SHA-1 that returns the same value in "normal" cases and 
different-but-secure values on attack vectors can be substituted.
