I agree with samtregar's advice to just store pathnames in the database....BUT assuming you know what you are doing, I think I would use base 128 encode them 
#!/usr/bin/perl
use warnings;
use strict;
use Math::BaseCnv;
#fast

my $time = time;
print "time -> $time\n";          

my $time_128 = cnv( $time, 10, 128 );
print "time_128 -> $time_128\n";
#this will sometimes print hidden newlines

my $time_back = cnv( $time_128, 128,10 );

print "timeback-> $time_back\n";
exit;
