Great! But.... I was hoping it would do DNSSEC by now.

Like Bert's  tool has been doing for ages:

dig 2.3.*.2.+.rp.secret-wg.org TXT +dnssec

http://bert.secret-wg.org/Tools/index.html

I'd be glad to know how long that's been up (mine was posted in 2001 for the Sigcomm OO session). AFAICT, that web page was put up in 2003, but I'd be glad to hear otherwise.

Some key differences, FWIW:

        - my variant returns the response as an IP address,
        rather than inside a TXT record (there's a point to
        that, as per the OO slides posted on the page above)

        - the Bert version uses DNS strings that aren't valid
        (*, +, ',', ++)

        - my variant has a static number of entries (40,003).
        That's intentional to avoid potential impact on
        DNS caches.
