Discussion on security focus:

Individual understanding:

1. First cracking this thing is relatively high, the general people cannot achieve. "On the IBM P690 host", the IBM P690 is not a general user tool;

2. This algorithm only said that it reaches M ', N' with your original M, N after some algorithm, can get the same HASH, lose MD5 algorithm uniqueness, the previous so-called security is not safe;

Therefore, it is also limited that the above can be said. Most of the network is still safe, unless verified, this is to pay attention to.

However, the words are coming back, this is really paying attention, I don't know what the two studies have come out!

PS: It is actually a crack is a female doctor and a academician. It is really nb.
