* 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 .
