Re: [ciphertool-devel] common cryptanalysis resources

[Wart <wa...@ko...>]

That sounds like a good idea to me.  ciphertool already has a format for
storing this kind of information.  While the syntax looks very Tcl-ish,
it can be easily parsed in any language.  Alternately, I wouldn't be
opposed to changing the ciphertool file format to make it more friendly
to other languages.

Here's an example of the current format:

type    aristocrat
period  0
ciphertext     
{qeceoemechkdioenkroczkdngxgwnefezrnkyirocdqeceinrubewzdmnbgmmhiuepruinwrqvynwgjgwikezgxgwneinyfhejvgdwfi}
plaintext       {pogonology has nothing whatever to do with using a pogo
stick or walt kellys comic strip but refers however to study of beards}
key     {abcdefghijklmnopqrstuvwxyz { kgaodeysfh ltnmpi  cbrvuw}}
language        english
keyword {abcdefghijklmnopqrstuvwxyz { kgaodeysfh ltnmpi  cbrvuw}}
# Digram value:  0
# Trigram value:  0
# K1 key:   kgaodeysfh ltnmpi  cbrvuw
#          abcdefghijklmnopqrstuvwxyz
# K2 key:  dvufgjckr bmpoeq winyxz h 
author  g-man
title   {Not what you might think.}

Each line contains a key/value pair separated by whitespace.  Curly
braces can be used to enclose the value if it contains whitespace.  A
single key/value pair must be all on the same line; they can't span
multiple lines.  Lines beginning with '#' are comments that can be
ignored.  A well known set of key values is used by the various
reading/writing programs to maintain consistency:

type
period
plaintext
ciphertext
key
keyword
author
title
language

Other keys can be used, but these should be a standard set used in all
files.

Feel free to make suggestions on how to improve it.  I've got a few
ideas, but I'd like to hear from others first.
