Tool to write text as a route. Route cipher is a transposition cipher method which consists in reading letters in a text according to a predifined route/path, as a serpentine road.

Route cipher encryption consists of writing the text following a path/route often using laces (or serpentines). This type of writing is adapted to the use of a grid because it can be written on N columns, the first from top to bottom then the second from bottom to top and so on.
Example: The text DCODEROUTE, on a grid of height 3 read by row becomes DRO-CEU-ODTE
If the message does not fill the grid, add a character like - to end the column/row.
Decryption requires knowing the path (or at least the size of the grid) in order to write the letters of the message.
Example: The encrypted text PIN-AFD-THER on a grid of height 3 is written as
Example: The grid path reading returns PATHFINDER
The best method is to try diffrent sizes and try to see if the beginning of the message is readable. dCode allow testing multiple possibilities automatically in order to detect the most probable.
On a grid of a given size, it is possible to write the text in the path of at least 8 (classical) ways (there are 2 possible directions for each of the 4 corners). Then reading can be a path too.
It is possible to imagine any type of path for letters, such as a spiral script. Another variant is Caesar box cipher.
