L_DicomSetCipherToIndexTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomSetCipherToIndexTLS(hNet, nIndex, cipher)

HDICOMNET hNet;	/* handle to an existing DICOM Network */
L_UINT32 nIndex;	/* index into an array */
L_CIPHERSUITE cipher;	/* ciphersuite */

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

Returns

DICOM_SUCCESS	Success.
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.
