L_DicomGetIntegrityAlgorithmTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomGetIntegrityAlgorithmTLS(hNet, cipher)

Returns the message authentication code type (MD5, SHA) for the cipher.

Parameters

HDICOMNET hNet

Handle to an existing DICOM Network. This is the handle returned from the L_DicomCreateNet function.

L_CIPHERSUITE 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_NONE	[0x00] Returned if no secure connection is established.
L_MAC_SHA1	[0x10] Secure Hash Algorithm (New and improved algorithm)
L_MAC_MD5	[0x11] Message-Digest algorithm 5

Comments

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