As soon as I woke up, the world changed. Collisions for hash functions md4, MD5, HAVAL-128 and ripemd.

Security focus:

Personal Understanding:

1. First of all, cracking this item requires a high level of hardware, which generally cannot be achieved. "On the IBM p690 host", the IBM p690 is not yet a tool for normal users;

2. This algorithm only means getting a new m', n' and your original M, N can get the same hash through some algorithms, without the MD5 Algorithm uniqueness, previously, the so-called security is no longer safe;

Therefore, the above can be said to be cracked only limited. At present, most of the network can still be secure, unless something is verified, this should be noted.

However, I have said it again, so I do know what the two research will do in the future!

PS: what actually can be cracked is a female doctor and an academician. It's really Nb.
