I came up with the following idea.
 
Register a webpage at nekoweb.org, use an API key
and send encrypted messages to the web page, which
later Bob and Alice can decrypt.
 
https://pollux.nekoweb.org
 
Alice does:
 
$ xchacha20 key iv < msg.txt | b2h | hex2img -b 0 -v | xml2html > index.html && neko
 
Process completed in 4.7553ms

While Bob does:
 
$ curl https://pollux.nekoweb.org | xml2html -d | hex2img -v -d | b2h -d | xchacha20 key iv

Hello sci.crypt! :-)

Thus allowing Alice and Bob to exchange messages without email usage and
without visiting a website with a browser.

I figured out that my xml2html program is not required, because the xml/svg
output renders just fine on web pages, with Edge Browser. Hope this is true
as well for other browers.

I also put the commands in aliases so that I only use 'enc' or 'dec' along
with the nekoweb command.

Example.

key: 5c42a3c290c91c66654b9af5a924057677b691257a24b7e414d028300bd4f6f0

$ enc | nekoweb msg/3.html

$ nekoweb -d https://pollux.nekoweb.org/msg/3.html | dec
I wish the sci.crypt community a nice weekend
and hope that you come up as well with such
an encoder/decoder! Best regards Stefan. :-)
