L_DicomSetCipherToIndexTLS

Summary

Sets the ciphersuite for the specified index.

Syntax

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomSetCipherToIndexTLS(hNet, nIndex, cipher)

Parameters

HDICOMNET hNet

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

L_UINT32 nIndex

Position in an array for which to set the specified ciphersuite. The ciphersuites in this array are those known by the client and should be ordered by preference.

L_CIPHERSUITE cipher

Value that indicates the ciphersuite to set at the specified index. For a list of possible values, refer to L_CIPHERSUITE.

Returns

Value	Meaning
DICOM_SUCCESS	The function was successful.
DICOM_ERROR_PARAMETER	A parameter error occurred. Refer to Return Codes.

Comments

The server chooses the first ciphersuite proposed by client, which it can understand. If the client puts the ciphersuites with reduced security first, then a ciphersuite with reduced security will most likely be selected by the server.
