* authdes.c - dummy encryption routines for destinations outside the USA.
*
* Sorry, folks; I hate this, too. Send me your e-mail address in an
* envelope bearing a US postmark and I'll send you the decryption key
* for the des program normally distributed with Unix in the USA. Outside
* the USA you are on your own; however, you should be able quickly to
* obtain the source from lots of places, homegrown or otherwise.
*
* to decrypt the des routine, mumble the following:
*
* des -d -k key authdes.c.des authdes.c
*
* , where key is as above, and rebuild. To restore the distribution
* to its exportable state, copy this file to authdes.c .
