[Jjeje007]

Hi,

See you,

I am on vacation next week so I will have a little free time to look into it. Thanks for the report.

[bofh28]

The command you want should be:
crunch 3 3 -m mom dad sister

There is no -h option.

Also there is a Makefile included that you should use instead of specifying your own options. There is no benefit to specifying -march as crunch is not processor dependent. The same is true for the -O2 option.

If you have any problems please let me know.

Thanks,

Hi bofh28.

I relay love your script, it's kinda JTR, but what i am relay missing is resume sesion just like JTR has it.

Can you please implement this in program?

I will see what I can do on my next vacation, which unfortunately won't be for awhile

This will slow it down a bit, and isn't the best solution but I figure if I start it people seem to come play golf and fix it, which will hopefully reduce some of your workload later . PseudoCode:

printf("%s", currentPassword);
emptyFile(file);
fwrite(file, "CONF:%s", configurationOptions);
fwrite(file, "%s", currentPassword);
...
resume() {
   fread(file, configurationOptions);
   fread(file, currentPassword);
   return currentPassword; // configurationOptions is a global
}
