partner, while for the remote SSL FTP partner the HP NonStop SSL proxy acts as a RFC-2228 compliant secure FTP
server or client.
Secure Proxy for EXPAND-over-IP
HP NonStop SSL running in EXPANDS mode encrypts EXPAND over IP traffic between two NonStop systems. It does
so by creating a secure SSL session between the two systems as depicted in the following diagram:

The EXPAND line handler will exchange UDP traffic with an instance of HP NonStop SSL running on the same
NonStop system; the two HP NonStop SSL processes create an SSL TCP session between the two systems to forward
the traffic.
Secure Proxy for ODBC Drivers
HP NonStop SSL can encrypt traffic between an ODBC driver (ODBC/MP, OBDC/MX, JDBC/MP and JDBC/MX) on
client workstations and NonStop systems.
Since ODBC/MP only uses a single TCPIP session, it can be enabled for SSL as described under "Secure Proxy for
Generic TCP/IP Client/Server Protocols".
In contrast, ODBC/MX, JDBC/MP and JDBC/MX use multiple TCP/IP sessions with different port numbers between a
single client and the NonStop system. However in conjunction with the RemoteProxy component on the Windows client,
HP NonStop SSL "tunnels" multiple sessions over a single one as shown in the following diagram:
