  * I have included directive PARA for shared memory computers.

  * I have included a directive LONGCRYPT to using this routine to cipher

  * passwords with more then 8 bytes like HP-UX 10.x it used. The MAXPLEN

  * definition is the maximum of length of password and can changed. I have

  * defined 24.
