I could be going it alone (in which case: sorry); but I don't seem to understand what doesn't work or what it is that you intend undef $/ to do. I don't think $/ applies in any way when using DBI, but I could be mistaken about that too.

Do you want to somehow escape the newlines before writing them to ki_file.txt?

You'd have to pick some standard way to do so if that's what you're intending. Personally, I'd probably choose to dump a hex or base64 representation to file: 

# note that part of your trouble could be your antiquated file-handle 
+representation (doubtful).
open my $output_file, ">", "ki_file.txt" or die $!;

# unpack can be a little arcane...
print $output_file unpack("H*", $ki_token), "\n";

The best document on unpack is actually pack. Please correct me if I've completely missed the point of the question.
