My fun and humble approach to convert German text messages
to fake OTP (One Time Pad) messages.

As an example, here is a small German text, saying if it
is possible to thwart modern text analysis software, to
detect who the author was. Padding was done manually, so
that we always have five letter code groups:

-----
Guten Morgen allerseits.

Vielleicht könnte man damit auch solche modernen
Forschungsprojekte durcheinanderbringen, welche
es 'Forscher' erlaubt Textanalysen zu machen?

Egal, es macht jedoch sehr viel Spaß mit solch
einem Script Text(e) zu manipulieren. :-)

Now we run a Linux one liner to convert the above text to
a fake OTP message.

cat message.txt | konwert UTF8-ascii/de | tr -cd '[:alpha:]' | tr [:lower:] [:upper:] | fold -w 5 | paste -sd' ' | fold -w 60

                               ^^^^
If we apply then a final '| rot13' at the end of the above
one liner we get this result, looking like an OTP message.

Additionally (Windows WSL) users can then run this program
to get a hard to recocnize (for computers) result, ready to
be FAXed:
