[split] Diplomatic ciphers

[ReneZ]

There is one distinctive feature that is never mentioned, but it is very important.

These ciphers were used to encode individual documents / communications between two persons, or two very small groups of persons. Both sides had the 'key'. They could have several such keys and would need to know which one to apply. (Nowadays, communication of the 'key' is more difficult than communication of the encoded message.)

These ciphers would not be used just to encode something without having a very specific, very well-identified recipient in mind.

It is left to Mark to explain how this fits with his theory, and with the possible purpose of the Voynich MS.
