L_DicomGetAuthenticationAlgorithmTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomGetAuthenticationAlgorithmTLS(hNet, cipher)

HDICOMNET hNet;

handle to an existing DICOM network

L_CIPHERSUITE cipher;

ciphersuite

Returns the mutual authentication mode or algorithm for the cipher.

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 authentication mode or algorithm.

Returns

A value that represents the authentication mode or algorithm. Possible values are:

Value

Meanin

L_MUTUALAUTH_NONE

[0x00] No mutual authentication.  Returned if no secure connection is established.

L_MUTUALAUTH_RSA

[0x20] Mutual authentication through RSA certificates.

L_MUTUALAUTH_DSS

[0x21] Mutual authentication through DSS.

L_MUTUALAUTH_DH

[0x22] Mutual authentication through DH.

Comments

There are several different cipher suites. Some differ only in the mutual authentication algorithm. Usually the authentication algorithm is based on RSA or DSS certificates.
