# How to decode a caesar that goes to transposed plaintext?

When decoding vigeneres, I am left with Caesars. Often when the key is longer, these are shorter so normal frequency analysis won't work.

Is there another method I can implement without adding a load of loops?

The most frequent letter will probably still be e or t, this uniquely determines the ceasar shift, this leaves maybe a few options. You can also do a $\chi^2$ test to match the alphabet in the subcipher with the standard one, or use bigram frequencies to rate combine shifts in adjacent alphabets.
