ok, i succeed to store and retrieve the data and also print it as a hash
(thanks...)
but i can't move it on the Socket, because it's a reference to a hash used
as a string ...
i need the hash to reach the client side...
i think i miss something here...maybe you will know..
thanks

That's obviously correct in the simple case, but how secure
serialization is ultimately depends on what the remote (or other,
or same-at-a-later-point-in-time, etc.) deserializing process *does*
with the data.

Ran said "read up on serialization", and I completely want to stengthen
his recommendation, but since Storable came up I want to add: please,
please, please use "nstore", and not "store". This should really have
been the default.
