LDicomNet::GetKeyExchangeAlgorithmTLS

#include "ltdic.h"

L_UINT32 LDicomNet::GetKeyExchangeAlgorithmTLS(cipher)

/* ciphersuite */

Returns a value that represents the key exchange algorithm. This function is available in the PACS Imaging toolkits.

Parameter	Description
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.
