This seems like "cryptanalysis, circa 1600".

Indeed. Caesar Ciphers seem to be the hardest it gets. Did you notice that this gang cryptanalyst actually described the famed "ROT-13" as a method the gang members used?

Triple rot13 (like Triple DES) is government approved.

    echo -n word | \
    > wm --rot13 --words stdin | \
    > wm --rot13 --words stdin | \
    > wm --rot13 --words stdin    

    result: jbeq

However, the result is the same as a single round.

    echo -n word | wm --rot13 --words stdin

    result: jbeq
