(Blowfish) Virus Protection

Hopefully this will lift your spirits a little bit (if you’re a techie, anyway).  Here’s a quick snap of the tabletop, taken this morning while my better half was taking a break.

A section of the OpenBSD "Blowfish" T-shirt being cut up for use as a facemask

Just in case you don’t know what you’re looking at, it’s her workspace, which is currently dedicated to producing DIY face-masks and the donor material is an iconic, OpenBSD “Blowfish” T-shirt.  This shirt had a picture of Puffy on the front, along with the text:- “So long and thanks for all the passwords”.  The back was what contributed to it becoming mildly infamous at the time, as it was printed with the Blowfish algorithm and was (allegedly) illegal to export from the U.S. (although I don’t remember ever hearing of anyone being arrested for walking through customs wearing one).

So, what used to protect your ssh tunnel‡ is now helping to protect (in a small way, I know) against the SARS-CoV-2 virus and, just in case it’s still on the banned list (and we ever get to travel again), the offending algorithm will be folded into the inside of the mask, keeping our secret safe.

 


 

‡  —  If you’re still using Blowfish, you should know that Bruce Schneier, the designer, now recommends upgrading to “Twofish”.
