The fact that you can construct pairs of strings with matching md5
hashes does not mean that you can find a string with the same md5 hash
as a given string.

The existence of this algorithm is disturbing, since it implies that MD5
is weaker than people thought, but it IS NOT a useful password cracker,
and there's no reason for immediate panic.
