I can't see anything wrong with your code. Dumb question time: is one of the $hashkeys that you print in the foreach loop and exact duplicate of "$issuer" . ".PUBLIC"? If not, you'll autovivify the hash entry, which I am guessing will be written to the file, but of course have no value. As a result, you'll have nothing in $val.

Show us your output. What's in $issuer? We'll need to see that to really give good feedback.
