No, there is not.
Hashtopolis is effectively for hashcat only. There is documentation of
what it expects from a password cracker, but I'm not aware of any other
password cracker (besides hashcat) supporting those options yet. We're
talking about --keyspace, --limit, --skip.
It might be possible to replace the need for --keyspace by (different)
usage of JtR's --node option, by allocating a huge number of virtual
nodes and using them as portions of work rather than actual nodes.
I did this with my own Perl scripts used in contests 10+ years ago.
--limit may be same or similar to our --max-candidates option.
We do not have an equivalent of --skip, but I think I saw code in
Hashtopolis itself where it'd simply use the "head" and "tail" commands
instead of --limit and --skip.
Someone very familiar with Hashtopolis (which I've never used) may make
an attempt at proper integration with JtR and let us all know.
