Strange problems with Tie

[tame1]

I am currently working on a script which involves some RSA encryption, as well as MD5 work.

Here is the troublesome subroutine:

sub get_pubkey {
    my $issuer = shift;
    my %hash;
    tie %hash, 'BerkeleyDB::Hash', -Filename => "/home/httpd/newkeyrin
+g" or die "Cannot tie the hash to that file: $! $BerkeleyDB::Error\n"
+;
    open(TEST, ">> fields_data");
    foreach my $hashkey (keys %hash) {
        print TEST "The pubkey is: $hashkey\n";
        print TEST "The value is: $hash{$hashkey}\n";
        print "The pubkey is: $hashkey<br>\n";
        print "The value is: $hash{$hashkey}<br>\n";
    }
    my $server = "$issuer" . ".PUBLIC";
    my $val = $hash{$server};
    close(TEST);
    untie %hash;
    print "Server is : $server<br>\n";
    print "Public key currently is: $val<br>\n";
    return $val;
}

Everything seems fine (It all prints out - %hash only contains 2 keys and 2 values) until the final print of the Public Key - THAT comes up blank. $server is set fine, but $val is empty. The sub also returns nada. Can anyone see what I am doing wrong to cause this?

open(TEST, ">> fields_data");

*grumble* Always check the rsult of system calls...moving on.

The keys in the hash are not what you think they are. If print "$foo{$key}" says one thing, but later on $key="X", $val=$foo{$key} says another, then you're $key's aren't the same in both places. Simple as that. (or the DBM is whacked.)

In your diagnostics, put some quotemarks around the keys as you print them. Check for unprintables too.

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.

***BLUSH***

Turns out there was a non-printing character difference in the keys.
