Hashes are as different as cryptographic routines. Finding weaknesses in one does not necessarily indicate a weakness in others. "cows" I predict by 2020 that all the hashes that we have today will have been broken and if i am wrong i will give Donald Ł20 Ha! Keep your money. It's possible that SHA-256 has weaknesses as well, I don't know enough about hashes to say. But it's important to realize that hashing is (as far as I know) a fairly NEW science. We went from simple check-sums to MD5 and then to SHA-1. There is still a lot to learn here, especially in how to evaluate the security of a hash. So, since our problem is ignorance about hashes and one way functions, I would be almost as nervous betting that SHA-256 is breakable as betting that it isn't. Donald
