It looks like you'll have to modify In my version (2.14), the 'finish' method deletes the current IV.
delete $self->{'civ'}; delete $self->{'buffer'}; return $result; }
You'll have to prevent that from happening, and then add a method to return the current (last) IV, instead of the initial IV
sub get_civ { return $self->{civ}; }
I have no idea if or how this affects the security of the two messages.

Hope this helps, J
