L_DicomGetIntegrityAlgorithmTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomGetIntegrityAlgorithmTLS(hNet, cipher)

HDICOMNET hNet;	/* handle to an existing DICOM Network */
L_CIPHERSUITE cipher;	/* ciphersuite */

Returns the message authentication code type (MD5, SHA) for the cipher. 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.
cipher	Value that indicates the ciphersuite for which to get the message authentication mode or algorithm.

Returns

A value that represents the message authentication code type. Possible values are:

Value	Meaning
L_MAC_SHA1	[0x10] Secure Hash Algorithm (New and improved algorithm)

Comments

There are several different cipher suites. Some differ only in the MAC algorithm.
