Collision of the compress function of MD5

[Guilherme]

Take a look:

What is the difference between the "collision of the compress function of MD5" and the collision that MD5CRK is searching for?

[Digital Parasite]

The compression function is an internal part of the MD5 algorithm. So finding a collision in the compression function was the first sign that MD5 might not be that great. That in itself doesn't break the algorithm though.

MD5CRK is trying to find a collision in the entire MD5 algorithm.
