Returns a value that represents the key exchange algorithm.
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 key exchange algorithm. |
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 |
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.
