L_DicomGetKeyExchangeAlgorithmTLS

#include "ltdic.h"

L_LTDIC_API L_UINT32 L_DicomGetKeyExchangeAlgorithmTLS(hNet, cipher)

Returns a value that represents the key exchange algorithm.

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 key exchange algorithm.

Returns

Value that represents the key exchange algorithm. Possible values are:

Value Meaning
L_KEYEXCHANGE_NONE [0x00] Returned if no secure connection is established.
L_KEYEXCHANGE_RSA_SIGNED_DHE [0x40] RSA signed Diffie-Hellman ephemeral.
L_KEYEXCHANGE_RSA [0x41] RSA key exchange
L_KEYEXCHANGE_DH [0x42] Diffie-Hellman key exchange
L_KEYEXCHANGE_DH_DSS [0x43] DS/DSS (Digital Signature Standard/Diffie-Hellman) key exchange
L_KEYEXCHANGE_FORTEZZA [0x44] FORTEZZA key exchange

Comments

The key exchange algorithm is the algorithm for securely generating secret keys.

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

Required DLLs and Libraries

Platforms

Win32, x64.
