Is there any easy way to crack a Beaufort cipher?

We have a Vigenère table, and are trying to guess the keyword.

Any easier way?

Yes (guessing you are doing the cypher challenge?)

The "Beaufort Decoder" is a really good decoding tool (saves you time), then trial and error keywords. Also, the "Vigenère cracking tool can be used to find the length of the keyword. Paste the texts you're decoding; the number of the column(s) with the most x's is the length of the keyword.

There is an online tool available which cracks vigenere, beauford and autokey ciphers: http://www.guballa.de/pages/geocaching/vigenere-solver.php
