- \version $Id: asdcp-wrap.cpp,v 1.5 2012/03/07 18:47:02 mikey Exp $
- \brief AS-DCP file manipulation utility
-
- This program wraps d-cinema essence (picture, sound or text) in t an AS-DCP
- MXF file.
-
- For more information about asdcplib, please refer to the header file AS_DCP.h
-
- WARNING: While the asdcplib library attempts to provide a complete and secure
- implementation of the cryptographic features of the AS-DCP file formats, this
- unit test program is NOT secure and is therefore NOT SUITABLE FOR USE in a
- production environment without some modification.
-
- In particular, this program uses weak IV generation and externally generated
- plaintext keys. These shortcomings exist because cryptographic-quality
- random number generation and key management are outside the scope of the
- asdcplib library. Developers using asdcplib for commercial implementations
- claiming SMPTE conformance are expected to provide proper implementations of
- these features.
