RE: 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. A preprint was circulating at the RSA conference; Adi Shamir had a copy. Similar techniques were used by Vincent Rijmen and Elizabeth Oswald, in their paper available at .http://eprint.iacr.org/2005/010.

* Jack Lloyd: http://theory.csail.mit.edu/~yiqun/shanote.pdf 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. - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
