He shouldn't have used dynamic_66 anyway;
Since mentioning this in doc/DYNAMIC doesn't seem to be good enough,
should we also add a comment mentioning that names up to dynamic_999 are
reserved? The patch does that for dynamic.conf.
I also noticed that the documentation for dynamic formats wasn't really
up to date.
I tried to improve that a little bit with my patch. Please have a look.
Probably more can be done here.
Some of the Examples included in doc/DYNAMIC are syntactically not
correct, and john will complain about errors:
(But may be the errors existed for a long time, and we have more
important errors to fix.)
$ ./john --test=0
Error, unknown function:
Func=DynamicFunc__SHA1_crypt_md5_input1_append_input2_base16
Error parsing section [List.Generic:dynamic_1062]
Error in line 1638 file is ./john.local.conf
After commenting out that one:
$ ./john --list=subformats
Error, unknown function:
Func=DynamicFunc__SHA1_crypt_md5_input2_to_output1_FINAL
Error parsing section [List.Generic:dynamic_1063]
Error in line 1654 file is ./john.local.conf
BTW, [List.Generic:dynamic_1062] and [List.Generic:dynamic_1063] both
appear twice in doc/DYNAMIC.
1064 is incorrect as well.
$ ./john --list=subformats
Error, unknown function:
Func=DynamicFunc__SHA1_crypt_md5_input1_to_output1_FINAL
Error parsing section [List.Generic:dynamic_1064]
Error in line 1665 file is ./john.local.conf
BTW, if I just comment out the line
Func=DynamicFunc__SHA1_crypt_md5_input1_to_output1_FINAL
and delete all other formats after dynamic_1064,
./john --test=0 --format=dynamic_1064
will segfault.
And so on.
May be for jumbo-6, I'll just add a cleanup patch deleting the incorrect
examples from doc/DYNAMIC.
If someone wants to add correct examples, this should be easy by
fetching the old revision.
Frank
