Obviously in the last day or two, I have been updating the website. As part of that process I deleted the half implemented Jekyll version and moved over to Hugo with the purehugo theme. That resulted in me deleting the keybase.txt proof.
Shortly after publishing the updated version of the site, keybase.io emailed me to give me the heads up that the proof was missing. I was quickly and easily able to replace the file, then log into keybase and once again prove that I own the shand.ca domain.
So should you need to send me something securely you should now have the means to do so.
