Creating an ADFGVX cipher

This cipher is obvious by the composition of its ciphertext - only 6 letters ADFGVX and it isn't easy to decipher. It uses a 6 * 6 grid of characters to substitute for the 26 letters and 10 numbers (optional) of the plaintext. The letters A D F G V X are used to create 36 double chars eg. AD AF VV FX and so forth. By referring to this grid the plaintext is converted into a set of these characters giving a stage 1 ciphertext. This ciphertext is then transposed by using a keyword that is written in the first row of a new grid with the ciphertext arranged accordingly. The columns of the grid are then arranged so that the keyword letters are now in alphabetic order which gives the final ciphertext
