SHA-1 results available
http://theory.csail.mit.edu/~yiqun/shanote.pdf No real details, just collisions for 80 round SHA-0 (which I just confirmed) and 58 round SHA-1 (which I haven't bothered with), plus the now famous work factor estimate of 2^69 for full SHA-1. As usual, "Technical details will be provided in a forthcoming paper." I'm not holding my breath. -Jack
