More info on the underlying encryption scheme can be found at http://en.wikipedia.org/wiki/Vigenère_cipher -- a local discussion of some related aspects (/tabula recta/) is at http://www.portablefreeware.com/forums/viewtopic.php?t=16674 ...

XOR+ v1.00.1b

dmg on 6 Feb 2014
  • 416KB (uncompressed)
  • Suggested by dmg

XOR+ is a text cipher application meant for entertainment / educational purposes. It enciphers and deciphers text using a simple XOR cipher, followed by multiple transposition, homophonic substitution and obfuscation steps.

This program is not intended to perform any actual security function. XOR+ is a modern variant of the decoder rings that used to come in cereal boxes: fun and not to be taken seriously.

What's new?
  • FreeMat is now (hopefully) easier to build. The top level README.TXT includes instructions on how to build FreeMat on all three platforms (Linux, Mac OS X, and Mingw32)
  • Documentation has been migrated to doxygen
  • A number of improvements have been made to the JIT back end
  • 64-bit on all platforms
  • Fixed path detection problem on win32 (forward vs backward slashes)
  • Added ability to change the scrollback length via edit->preferences menu
  • Fixed diary command so that commands are echoed as well as their outputs
  • Fixed diary so that the commands are echoed as well as the outputs
  • Added fflush command
  • Added ctrl-w to clear the current line
  • Changed sort algorithm to a stable one
  • Fixed bug in linspace for linspace(0,60000,60001)
  • Patched ctypewrite to use new ctype names
  • Converted FFTW to estimate mode from measure mode - should fix problems with long FFT times for large FFTs
  • Added more diagnostic output to ctypefreeze
  • Added stack trace on errors, even when not in dbauto on mode
  • Improved the autoconfig script for mac builds
  • Finished ctype interface - works as expected
  • Moved loadlib and import to external documentation section
  • Added external section to the documentation
  • Changed the default mode for "image" command" to "scaled" instead of "direct". This is less compatible with MATLAB, but I don't think it's unreasonably so
  • Added "edit" command
  • Changed default type for zero function to double precision
  • Added imagesc command. Modified image command to show un-scaled images

FreeMat is an interpreted, matrix-oriented development environment for engineering and scientific
applications, similar to the commercial(expensive)package: MATLAB.

There are free clones of MATLAB available (totally legal and free) and can be downloaded from the web,
one of my favorites are FreeMat.
FreeMat is a free open source numerical computing environment and programming language,
similar to MATLAB and GNU Octave, is available for multiple operating systems, Windows, Linux and Mac
An advantage of Freemat is the convenient mechanism of loading shared libraries written by other
language (it features a codeless interface to external C, C++, and Fortran code)
