Zkdecrypto-lite Zkdecrypto-lite is one of the most amazing tools I have ever seen. It will almost instantly solve homophonic ciphers. You just won't believe this tool. Includes many famous ciphers. A more extensive description is here.

A selection of Linux distributions; I didn't include Ubuntu, since I linked to it elsewhere. Your distro will include OpenOffice or LibreOffice, R, bash, Perl, and other needful tools.

Things from me

Here's a sample bash script to run zkdecrypto-lite in batch mode on the restricted 340 cipher text:

 #!/bin/bash  
 COUNTER=$((0))
 NUM=$((0))
 while [  $COUNTER -lt 50 ]; do
    NUM=$((40*COUNTER))
    echo Iteration: $COUNTER Seconds: $NUM
 ./zkdecrypto-lite cipher/340.zodiac.nofake3.txt -t $NUM  >> zodiac-work-4.txt
    COUNTER=$[$COUNTER+1]
 done

This is the version which, fifty at a time, running overnight, created the 400 iteration file used for the main analysis (fifty iterations took about six hours):

 #!/bin/bash 
 COUNTER=0
    while [  $COUNTER -lt 50 ]; do
 ./zkdecrypto-lite cipher/340.zodiac.nofake3.txt -t 600 >> zodiac-work-2b.txt
    let COUNTER=COUNTER+1 
 done

Since it appends to the outputfile, it is possible to have any number of processes replicating the solutions.

And here's the 340 cipher file ('340.zodiac.nofake3.txt') itself:

340.zodiac.nofake3.txt

If you put this file into the "cipher" subdirectory in the location with zkdecrypto-lite, then run the above bash script, you'll get the results I got, appearing in the text file 'zodiac-work-4.txt.'

You can analyze the results by making a CSV file with the following Perl script, and then import the CSV file into the OpenOffice spreadsheet, or into R:

 #!/usr/bin/env perl
 use warnings;

 my @rows;

 open(my $fh, "<", "zodiac-400.txt")
     or die "Failed to open file: $!

";

 open(my $fh2, ">", "zodiac-400.csv")
     or die "Can't open > output.txt: $!

";

 while(<$fh>) 
     { 
     chomp; 
     $row = $_;
     $row = join(",",split(//,$row));
     print $fh2 $row;
     print $fh2 "

"; } close $fh; close $fh2;

And following is the result of the above, the spreadsheet with the 400 iterations worth of solutions, in CSV spreadsheet format.
