Subject: how to list not salted formats?
I tried to find all formats without salt. I tried to use 'Salt size'
from `john --list=format-all-details` but it turned out to be wrong
because some formats showed "Many salts" and "Only one salt" during
benchmarks.
For me it looks like there are 2 problems:
1) the following dynamic formats report "Salt size 0" while they
have salts:
dynamic_1011
dynamic_1012
dynamic_1013
dynamic_1014
dynamic_1016
dynamic_1401
dynamic_1502
dynamic_1503
dynamic_1504
2) mdc2 and pix-md5 report "Many salt" while they don't have salts. It
seems to be caused by the following line (in mdc2_fmt_plug.c and
pixMD5_fmt_plug.c ):
#define BENCHMARK_LENGTH 0
My command and output (I did s/--/---/ for email):
$ john --list=format-all-details | grep -e '^Format label' -e '^Salt size' | grep -B 1 '^Salt size *0$' | sed -ne 's/^Format label *// p' | while read -r f; do john --test "--format=$f"; done | grep -C 1 Many
