What's the shortest pair of strings that causes an MD5 collision?

Question

Up to what string length is it possible to use MD5 as a hash without having to worry about the possibility of a collision?

This would presumably be calculated by gen

Answer 1

I doubt if there is any useful length where you're not going to have possible collisions. Those algorithms are not really used for that purpose. It's meant to try to be unique for slight changes in the data (like corrupted files) rather than unique over all possible sets of data.
