Anonymous Monk,
I wrote a tutorial on this very topic. In your case you want to loop through the hash keys and probably use List::Util's first to determine presense in the array. 
for my $key ( keys %hash ) {
    if ( first { $_ eq $key } @array ) {
        # match logic
    }
    else {
        # no match logic
    }
}
