I can now reset the password on any .m file or within a .hst file, as long as the file only includes one turns worth of data.

It's trivial with raptor's files (if you actually know Java). Decrypt the file, replace 4 bytes, reencrypt the file. Anyone writing a utility that creates / rewrites Stars! files can in moments create a utility to reset Player passwords.

Re: processing .m files (and .hst files) with more than one turn.

A .m file with more than one turn is (effectively) each turn appended to the last (block structure 8,6,[n],0,8,6,[n].0,8,6,[n],0. etc.]

Anyone know if the encryption seed should be reset on each turn's worth of data?

I suspect the fMulti value (also in the FileHeaderBlock) might well come into play as well. The value for fMulti is either 0 (one turn) or 1 (more than one turn).
