Subject: Re: md5_gen(0) broken for ages?
Now I could reproduce it without Simons link from raw-md5. I had to use
longer input lines (with more fields).
$ cat test/testm.rawmd5
testcz:md5_gen(0)65775a4b0631c2b88117153163b921a0:123
testcz2:md5_gen(0)1826e74f4ab2a9c728b2f53445e0af6c:456

wordpress:md5_gen(0)1870a829d9bc69abf500eca6f00241fe:
$ rm -f deleteme ; ./john-jumbo12E1-intr test/testm.rawmd5 -inc:digits
-pot:deleteme
Loaded 8 password hashes with 6 different salts ( md5_gen(0): md5($p)
(raw-md5) [SSE2 10x4x3 (intr)])
...and this also happens with a much older version:
$ rm -f deleteme ; ./john-1.7.6-jumbo7 test/testm.rawmd5 -inc:digits
-pot:deleteme
Loaded 8 password hashes with 6 different salts ( md5_gen(0): md5($p)
(raw-md5) [md5-gen 64x1])
If you strip all fields after the hashes, it does not happen. So
currently we can not use single mode with md5_gen(0)!
And here is a separate problem: I can not load raw-md5 using
command-line format and subformat
$ cat test/test.rawmd5
