How do I add a dictionary like Rockyou?

[Kandeen]

For what purpose? So I know which encryption is being used?

The encrypted password does start with $P$, which should be md5(wordpress) isntead of md5(phpbb3) like in the exame you placed in your post.

However, it seems multiple people (like Atom) say md5(phpbb3) is the same as md5(wordpress)
