Thanks for the info! I had a quick look at the source code and
as understood it uses QR-Codes, which i have played also in
the past with.

However, i am currently interested in using codegroup armor
so that it can be printed too and then read properly (hopefully)
with OCR solutions.

Maybe a bit old fashioned, but worth a try imho, because
in case OCR fails one could type it in manually, if its are
short encrypted messages.
