Hi David -

Thanks for the quick reply.

I should note that I am on a Windows XP box.

When I run gpg --export-secret-key my at | paperkey  --output-type raw for both the 2048 and 4096, I note that the output for the 4096 key is about 10% logner than that of the 2048 key.

I am not familiar with wc.exe, but will google it...

Paperkey doesn't care what size the key is.  Try doing that same command line, but use "wc -c" instead of the dmtxwrite part to check that the output is larger than with a 2048 bit key.  Perhaps dmtxwrite is having a problem?
