Re: iSphere TN5250j SSL Problem

Jack,

I assume that you mean TLSv1.1 and TLSv1.2, right? I am not an SSL/TLS
expert but people often mix SSL and TLS. Wikipedia
(https://en.wikipedia.org/wiki/Transport_Layer_Security) mentions the
following protocols:

SSLv1.0
SSLv2.0
SSLv3.0
TLSv1.0
TLSv1.1
TLSv1.2
TLSv1.3

For TLSv1.1 and TLSv1.2, I get the "SSLContext not available" error:

24679 [Thread-10] INFO
org.tn5250j.framework.transport.SocketConnector -

29032 [Thread-10] WARN org.tn5250j.framework.tn5250.tnvt -

But of course these protocols should also work, if possible.

Tom, I currently do not use this tool, but wouldn't you want it to work for
SSLV1.2??

Hi,

Today I uploaded iSphere 3.0.0.b009, which enables SSL for the TN5250j
emulator. It works fine for RDi 9.5 and Java 7, but it does not work for
all other IDEs with Java 1.6 and lower.

For example I receive the following errors for WDSC 7.0:

TLSv1.1:

I already tried installing the "unrestricted policy files" to solve the
"RSA premaster secret error" as described here
"http://www-01.ibm.com/support/docview.wss?uid=swg21663373"; without
success. Maybe I did something wrong.

Maybe, that somebody of you can help solving the problem. I am stuck.

Regards,

Thomas.
