Hi all, i don't know how many of you folks use social media sites like Twitter and Facebook etc. and wondered what's a way to post a GnuPG clear signed message on those sites, due to line width limits or characters per message limits.
Well, i thought about that to and i like to share an idea with you. I found out that with short GnuPG clear signed messages a good way to do that is to encode the message in the popular QR-Code format. For this task i used the package "qrencode" which is available as Linux package and can also be compiled under OS X, for example. https://fukuchi.org/works/qrencode/ So, simply prepare your short GnuPG message and then do a: $ qrencode -o message.png < message.txt.asc, to obtain a .png image, ready to be posted on social media sites. To decode such an image in Terminal simply do a: (please note: the images when downloaded are then in .jpeg format) http://zbar.sourceforge.net/download.html $ zbarimg image.jpg > output.txt && sed "s/QR-Code:-/-/g" output.txt | gpg --verify If you know a better and shorter way to decode, please let me/us know. Hope you find this little tip useful and i hope it may spread the usage of GnuPG! :-) Regards Stefan -- https://www.behance.net/futagoza https://keybase.io/stefan_claas
