It is often said that the Voynich cannot be written in cipher as a 600 years old cipher would have been deciphered by modern cryptography by now.
However it seems to me that in practice it is very easy to create a "simple" cipher which is very hard to crack. For those familiar with Nick Pelling's Cipher Mysteries website it is apparent that there are lots of ciphers from different periods in time, though none as old as the Voynich, that haven't yet been cracked.
If I was creating a hard to crack cipher I would start with a preponderance of filler text, the more filler the harder to crack. However it would be interesting to see how others might go about producing a difficult to crack "simple" cipher.
(When I use the term "simple" cipher I mean one based on simple techniques or ideas. I don't mean modern ciphers based on modern mathematical techniques.)
