What you are talking about is serializing data ie take a hash, turn it into a string for storage/transport, reconstitute the hash. I tend to use Storable but here are lots of other serialisation options. See FreezeThaw, Data::Serializer, Data::Dumper and friends to name a few.

However CGI::Session will handle serialisation for you (you can select the Module to use for it as well). All you need to do is save a hash_ref, then you can restore a hash ref 

use CGI::Session;
use Data::Dumper;

my %hash  = ( foo => 1, bar => 2 );
my $session = new CGI::Session("driver:File", undef, {Directory=>'/tem
+p'});
$session->param(-name=>'hash', -value=>\%hash);
my $hash_ref = $session->param('hash');
print Dumper $hash_ref,
