US companies are required to get special licenses to export software
which may be used to encrypt data.  It has little to do with key length,
and more to do with the security of the chosen encryption method.  

The DCE Security Services (and Kerberos, and the AFS kaserver) use DES
to encrypt the *authentication exchange* but not actual user data.  The
US Govt has deemed this acceptable.  Although licenses must still be
obtained, there is a streamlined process in place. 

The DCE permits DES encryption of the user data, but most vendors are
packaging this as an add-on option which is only available to domestic
customers (or with the appropriate licenses).
