If you're referring to the assoc_handle values you see with some
servers, they are opaque identifiers generated by the server for its own
reference when looking things up in its store of secrets.  They are not
required to be structured or human-readable at all.  The convention
you're seeing here is something done by some of the implementations to
make debugging a little easier.
