It is possible that an application cannot handle the Automatic SSL version and Encryption Strength set by SilkPerformer by default and instead you will need to present the exact values that the site uses.
To determine which settings are needed you should check the SSL Version and Encryption strength in the client:
- In Internet Explorer: right-click on the page and go to Properties
- In Chrome: click on the padlock icon (on the left of the URL); a popup appears, which contains the details,
- FireFox does not display the SSL version.
For browsers which do not show the information, you can always obtain it by running a network analyzer.
Please note that the actual protocol version used will be the highest that both the client and server support.
Problems can arise with automatic detection of SSL version and Encryption Strength because
- the server is not configured to accept this
- the open ssl libraries is causing an error.
You can test this by running openssl.exe and typing
s_client -connect Mysite.com :443
if there is a problem with detection then an error will be returned.
You can then run the same command with the actual SSL Version specified e.g.
s_client -connect Mysite.com :443 -no_tls1_2
and see that the handshake now takes place
