I'm looking for ciphertext analysis tools --

What analysis tools did you use?  Where can I get a publicly available copy?

Thanks!

I just wrote a little c program for frequency analysis, but would
also be interested if such set of tools existed.

There are several tools for cryptanalyzing simple ciphers at ftp.ox.ac.uk/pub/
crypto/cryptanalysis and ftp.replay.com/pub/crypto/applied-crypto .  There
is also elisp code distributed with emacs that can solve a substitution
cipher.

Mark -- do you know what are the relevant file names?

I don't know them off hand.  The "applied-crypto" directory has a README file
which describes what each file is.  The cryptanalysis directory at
ftp.ox.ac.uk has some of the same files.  The filenames at that site are
mostly self-explanatory.
