V_ENCRYPT()
 Encrypt a Clipper string variable
-------------------------------------------------------------------------------

 Syntax

    V_ENCRYPT( <cString> )   ->    cGobbleTgook

 Arguments

    <cString> is any valid Clipper character string.

 Returns

    V_ENCRYPT() returns an ecrypted string with the same length as
    the original.

 Description

    V_ENCRYPT() encrypts a Clipper string based on the current key setting
    (see V_SETKEY()).  The string can later be V_DECRYPT()ed by using the
    same V_SETKEY() setting.

    V_ENCRYPT() encrypts a Clipper string so that it is not human readable.
    The encryption algorithm has not been designed to any particular
    specification, however, as the author of the algorithm, I would not
    want to be faced with the task of decrypting a string without the
    <key> with which it was encrypted (see V_SETKEY()).

 Examples

    LOCAL cSecure, cOriginal

    // Set the key to my dog's name.
    V_SETKEY( "Tally" )

    // Encrypt a character string.  Store the result in <cSecure>.
    cSecure = V_ENCRYPT( "Just try to decode <cSecure> without my dog." )

    // Later, decode the secured string with the help of my golden.
    // The call to V_SETKEY() is redundant because the program has not
    // terminated and it has not been set to a different V_SETKEY().
    V_SETKEY( "Tally" )
    cOriginal = V_DECRYPT( cSecure )
