Function Documentation

int main	(	int	argc,
		char *	argv[]
	)

bool ProcessMetadata	(	bool	DecryptMode,
		MetadataPtr	HMeta,
		BodyReaderPtr	BodyParser,
		GCWriterPtr	Writer,
		bool	LoadInfo
	)

Process a set of header metadata.

If encrypting a crypto context is added in each internal file package, otherwise crypto tracks are removed

Returns:

true if all OK, else false

bool ProcessPackageForDecrypt	(	BodyReaderPtr	BodyParser,
		GCWriterPtr	Writer,
		UInt32	BodySID,
		PackagePtr	ThisPackage,
		bool	LoadInfo
	)

Process the metadata for a given package on a decryption pass.

Returns:

true if all OK, else false

bool ProcessPackageForEncrypt	(	BodyReaderPtr	BodyParser,
		GCWriterPtr	Writer,
		UInt32	BodySID,
		PackagePtr	ThisPackage,
		bool	LoadInfo
	)

Process the metadata for a given package on an encryption pass.

Returns:

true if all OK, else false
