The DCE/3000 Security component of /usr/lib/libdce.a uses the Data Encryption Standard (DES) algorithm as
its default encryption algorithm. Because the United States DOD
restricts the export of DES software, DCE/3000 supports two binary
versions:
The International version of the software disables the RPC
data protection level privacy, disallowing
users the ability to encrypt their data in RPCs. If an application
specifies the privacy level of data protection
while using the international version of /usr/lib/libdce.a, the application receives an rpc_s_unsupported_protect_level error. This restriction does not apply to the Domestic
version.
