I agree with the wait and see. However, cmp_all is not called in the
current unstable either (prior to the bitmaps). Look at the code in
cracker.c
There is an outer if statement, on whether the format is salted or not. If
not salted, then the else route is taken, and within that block of code,
cmp_all is never called, and only the bin_hashes and cmp_one/cmp_exact is
used. I am not fully sold that is the right way, BUT that is how JtR has
been running forever (for a long time at least).
Like I said, it was news to me, and surprised me some. I thought the code
always something similar to:
crypt_all();
if (hash() && cmp_all()) {
foreach: if (cmp_one() && cmp_exact())
output found pw
}
But it is not that way for non-salted.
