Yes, hash collisions definitely occur. There is no such thing as collision-free hashes, and MD5 is definitely broken. Even though the author says they were 3 million MD5 hashes the second time, the first one he calls them SHA1 and MD5 hashes (even though SHA1 is considered weak too). I wonder what kind of hashes Apple is planning to use. Will it be whatever is made available to them or will they only accept (what is now considered) secure standards?
