NAME

       enigma - Puzzle game reminiscent of Oxyd

SYNOPSIS

       enigma [options] [levelfile.xml] ...
       enigma  [--assert]  [-d	path]  [--help]  [-l lang] [--log] [--nograb] [--nomusic] [--nosound] [-p file] [--showfps] [--version] [-w] [lev-
       elfile.xml] ...

DESCRIPTION

       The object of the game is to find and uncover pairs of identically colored Oxyd stones. Simple? Yes. Easy? Certainly  not!   Hidden  traps,
       vast mazes, laser beams, and, most of all, countless hairy puzzles usually block your direct way to the Oxyd stones.  Enigma's game objects
       (and there are hundreds of them, lest you get bored) interact in many unexpected ways, and since many of them follow the  laws  of  physics
       (Enigma's special laws of physics, that is), controlling them with the mouse isn't always trivial ...

       For more information, please refer to the manual or the project homepage: <http://www.nongnu.org/enigma/>!

OPTIONS

       --assert
	      Forces all debugging assertions, even expensive ones, to be evaluated.

       -d path, --data=path
	      Prepend another data directory to Enigma's search path.

       -h, --help
	      Display a list of available command line options and quit.

       -l lang, --lang=lang
	      Override the default language. The language is given in the common 2 character sequence as fr for French or ru for Russian.

       --log  This switch turns on logging of internal information to the standard output.

       --nograb
	      Do not use exclusive mouse/keyboard access.

       --nomusic
	      Start Enigma without background music. Sound effects will still be played.

       --nosound
	      Start Enigma without sound effects.

       -p file, --pref=file
	      Start Enigma with an alternative preferences file without the leading dot for hidden filenames.

       --showfps
	      Show the framerate (FPS) during the Game.

       --version
	      Print the Enigma version number and quit.

       -w, --window
	      Run Enigma in a window; do not switch to fullscreen mode.

USAGE

NAME

     enigma, crypt -- very simple file encryption

SYNOPSIS

     enigma [-s] [-k] [password]
     crypt [-s] [-k] [password]

DESCRIPTION

     The enigma utility, also known as crypt is a very simple encryption program, working on a ``secret-key'' basis.  It operates as a filter,
     i.e., it encrypts or decrypts a stream of data from standard input, and writes the result to standard output.  Since its operation is fully
     symmetrical, feeding the encrypted data stream again through the engine (using the same secret key) will decrypt it.

     There are several ways to provide the secret key to the program.  By default, the program prompts the user on the controlling terminal for
     the key, using getpass(3).  This is the only safe way of providing it.

     Alternatively, the key can be provided as the sole command-line argument password when starting the program.  Obviously, this way the key can
     easily be spotted by other users running ps(1).  As yet another alternative, enigma can be given the option -k, and it will take the key from
     the environment variable CrYpTkEy.  While this at a first glance seems to be more secure than the previous option, it actually is not since
     environment variables can also be examined with ps(1).  Thus this option is mainly provided for compatibility with other implementations of
     enigma.

     When specifying the option -s, enigma modifies the encryption engine in a way that is supposed to make it a little more secure, but incompat-
     ible with other implementations.

   Warning
     The cryptographic value of enigma is rather small.  This program is only provided here for compatibility with other operating systems that
     also provide an implementation (usually called crypt(1) there).  For real encryption, refer to bdes(1), openssl(1), pgp(1)
     (ports/security/pgp), or gpg(1) (ports/security/gnupg).  However, restrictions for exporting, importing or using such tools might exist in
     some countries, so those stronger programs are not being shipped as part of the operating system by default.

ENVIRONMENT

	   CrYpTkEy  used to obtain the secret key when option -k has been given

EXAMPLES

	   man enigma | enigma > encrypted
	   Enter key: (XXX -- key not echoed)

     This will create an encrypted form of this man page, and store it in the file encrypted.

	   enigma XXX < encrypted

     This displays the previously created file on the terminal.

SEE ALSO

     bdes(1), gpg(1), openssl(1), pgp(1), ps(1), getpass(3)

HISTORY

     Implementations of crypt are very common among UNIX operating systems.  This implementation has been taken from the Cryptbreakers Workbench
     which is in the public domain.
