Just the raw-md5 hashes (about 140 millions) are more than enough for
testing.
You could even just use a fraction of 1/16 of these hashes, e.g.,
LC_ALL=C grep "0$" raw-md5.hashes.txt > testdata-0
These should fit into memory on a decent computer, and when you finished
your tests on this sample, you can use the next set of test data to
verify how useful your strategy is on this one.
I changed the subject, because useful test data is not only needed to
generate .chr files and evaluate their quality, but for other cracking
strategies as well.
