Tagesschlüssel 1:
Kasten: A    Kasten: B
0 4 6 A      6 9 E 3
F 1 3 E      7 2 4 D
7 C D 5      1 C 0 5
B 2 9 8      F 8 A B
 
And to simplify the encryption/decryption process, we could
do it this way. We only mirror from a -> b and b -> a, like:
 
With the seriation from above and the example box a and b:
 
Ciphertext: 90 B4 E1 etc.
 
This doublebox hex variation with only mirroring is IMHO
easy and would allow to transmit small binary blobs. :-)

 
I have now four programs ready. :-)
 
1. dkh (Doppelkasten Hex = doublebox hex)
2. dks (Doppelkasten Seration = doublebox seriation)
3. dkt (Doppelkasten Tagesschlüssel = doublebox daily keys)
4. dkk (Doppelkasten Krypto = doublebox crypto)

Sample run with yesterdays's message and today's keys:
