repacking encrypted .xp3

[Lacan]

Hi, new here and I've got a question.

I've managed to extract .xp3 files that are encrypted using crass tool with dec=xror parameter, I've finished editing it but now I can't reincrypt it and package it back to .xp3 form. Crass can extract but it doesn't repack. I have insaine tools put I'm not quiet sure what the command line I need to use for the .bat file to encrypt and their faq on that is down for the moment. Anyone got any ideas on how to do this? Thanks in advance.
