Subject: Re: Cracking multi-word passwords

Hello,

Others in this list can provide much more detail but one good option you
have is to use JtR Prince mode which will do what you want.

You can try the following options --prince=dictionary --prince-case-permute
--prince-elem-cnt-min=5 --prince-elem-cnt-max=5.
The --prince-elem-cnt-min=5 defines how many minimum words from the dic
will be "combined" and the max the maximum ones. The prince-case-permute
will permute the first letter of each word.

You can read more about this mode under JtR doc folder in PRINCE file.

Hope it helps
Luis
