L_LTDIC_API L_UINT32 L_DicomSetDefaultSigningISCL(hNet, nSignMode)

HDICOMNET hNet;	/* handle to an existing DICOM Network */
L_UINT32 nSignMode;	/* type of message authentication code */

Sets the current message authentication code. This function is available in the Medical Suite toolkits.

Parameter	Description
hNet	Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.
nSignMode	Flag that indicates the type of message authentication code to be used. Possible values are:
	Value	Meaning
	DICOM_ISCL_MAC_NONE	[0x00000000]No message authentication code will be used.
	DICOM_ISCL_MAC_MD5	[0x00001441]A 128 bit MD5 message authentication code is transmitted with the message.
	DICOM_ISCL_MAC_DESMAC	[0x00004001]A 64 bit DESMAC authentication code is transmitted with the message.

Returns

DICOM_SUCCESS	The function was successful.
DICOM_ERROR_PARAMETER	A parameter error occurred. The message authentication code will be of type DICOM_ISCL_MAC_MD5. Refer to Return Codes.

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 L_DicomSetDefaultEncryptionISCL function.

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