Here is a very simplified version of my VMs encoding method that gives all of the essentials of how it works. A PDF version has been added to the MediaFire folder.
The plaintext word in this example is “and”.
1. The word’s letters are moved vertically to a position directed by the letter table.
2. The letters are moved to the right and reassembled vertically in the new order.
3. The word is returned to the horizontal.
4. The plaintext letters are replaced with Voynich letters.
The method is simple, elegant, and will decode as well as encode.
For some reason the text editor will not keep the formatting visible in the edit field, so I have replaced it with a jpg. Refer to the PDF for the entire entry.
Scroll down to the 14 April 2013 post to see the method using the actual letter table and a label.
