The following table lists and describes the parameters available in the Terminal Emulator
Security tab.
Parameter Description
SSL Version Select one of the Secure Sockets Layer (SSL) and Transport
Layer Security (TLS) protocol versions to use for the
connection:
SSL v3
TLS v1
By default,
TLS v1
is selected.
Server Certificate Select one of the following server certificate options:
Always Accept
Ask Before Accepting
By default, Always Accept is selected.
Preferred CipherSuite Select an available CipherSuite to use for the connection from
the drop-down list.
By default,
None
is selected.
The implementation of the SSL/TLS security connection relies on the implementation of Oracle
Java Secure Socket Extension (JSSE). JSSE is included as a standard component of JRE
Version 1.4 and higher. SSL Version 3.0 and TLS Version 1.0 are currently supported by iWay
Emulation Adapter (3270/5250).
iWay Emulation Adapter (3270/5250) uses its own trust store file to store server certificates.
The file is called iway_telnet_jssecacerts and will be created in the following directory:
<JRE-home>
\lib\security
If the
Always Accept
value is selected in the Security tab of the Telnet Designer for the Server
Certificate parameter or ACCEPTCERTIFICATE='1' is included in the RPC scripts, then an
unrecognized server certificate will be stored in the trust store file. If the
Ask Before Accepting
value is selected in the Security tab of the Telnet Designer for the Server Certificate parameter
or ACCEPTCERTIFICATE='2' is included in the RPC scripts, then a dialog window with the
certificate information is displayed and you must decide whether or not to accept the server
certificate.
