* Jack Lloyd:
Thanks for the pointer.
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.
In addition, there's no trace of the second-preimage attack some persons recently alluded to.
