Return the key exchange algorithm used to establish the secure
connection with the server.
The SecureKeyExchange property returns an integer value
which identifies the key-exchange algorithm used when establishing a
secure connection. This property may return one of the following
|No key exchange algorithm has been selected. This is not a
secure connection with the server.
|The RSA public key exchange algorithm has been
|The KEA public key exchange algorithm has been selected.
This is an improved version of the Diffie-Hellman public key
|The Diffie-Hellman public key exchange algorithm has been
|The Elliptic Curve Diffie-Hellman key exchange algorithm
was selected. This is a variant of the Diffie-Hellman algorithm
which uses elliptic curve cryptography. This key exchange
algorithm is only supported on Windows XP SP3 and later
versions of the operating system.
If a secure connection has not been established, this property
will return a value of zero.
