I have created some #NFTs in the past, but must admit I do not like the way how the whole #NFT stuff works. It would be much cooler if we could #Zap images, so that the person who send a #Zap could also own the image of the poster, but not the Copyright. Well, just a thought ...
BTW. Here are my NFTs: https://rarible.com/individualist
So, you send encrypted emails to your friends, with #GnuPG. What happens, if you have a #Government #Trojan, on your online device, which you can't detect?
A solution to this problem, is to send/receive encrypted #SMS from a device, which is not connected to the #Internet. Under Linux, you can archive this by installing #modem-manager-gui, with apt-get. Then you only need a surf stick, like a #D-Link DWM 222 and a small portable device, like a #GPD MicroPC.
And as software, you can use #FPE (Format Preserving Encryption) with a base(x) encoder/decoder, with a line length set to 0.
If the SMS is longer than 160 characters it will send multiple SMS.
And as SIM card one can purchase those cheap #Allnet flat cards, so that you don't have to pay for each SMS, you send.
Hope you find this tip useful!
