LDicomNet::SetDefaultSigningISCL

#include "ltdic.h"

L_UINT32 LDicomNet::SetDefaultSigningISCL(nSignMode);

L_UINT32 nSignMode;

/* type of message authentication code */

Sets the current message authentication code type. This function is available in the PACS Imaging toolkits.

Parameter	Description
nSignMode	Flag that indicates the type of message authentication code to be used. Possible values are:
	Value	Meaning
	DICOM_ISCL_MAC_NONE	No message authentication code will be used.
	DICOM_ISCL_MAC_MD5	A 128 bit MD5 message authentication code is transmitted with the message.
	DICOM_ISCL_MAC_DESMAC	A 64 bit DESMAC authentication code is transmitted with the message.

Returns

DICOM_SUCCESS	Success
DICOM_ERROR_PARAMETER	A parameter error occurred. The message authentication code will be of type DICOM_ISCL_MAC_MD5.

Comments

The message authentication code is encrypted using the current encryption mode before being sent and decrypted after being received. The current encryption mode is set using the LDicomNet::SetDefaultEncryptionISCL function.

The encryption mode and the message authentication code type must be the same for both the sender and the receiver.
