You could use Storable as a mechanism for serialising your hash into a scalar. I would recommend this approach as it's quite space-efficient. Much more so than, for example, Data::Dumper with $Data::Dumper::Indent = 0.

On the other hand, if Storable is space-efficient, it is because the data structure is written in a binary format. That means that you can't easily inspect the values during a debugging run, whereas you could with Data::Dumper.

Finally, Data::Dumper is dangerous for serialisation, because you recover it with an eval, which gives the bad guys a chance to Nasty Things™ to your system.
