Install OpenSSL

If OpenSSL is not already available on the server, you must install it.

1. Download OpenSSL from http://www.openssl.org/. Be sure to use the version of OpenSSL appropriate for the server version:

   Table 1. OpenSSL versions

   Server Product	Compatible OpenSSL Version
   IBM® SPSS® Statistics 29	1.1.1f or later
   IBM SPSS Statistics 28	1.1.1f or later
   IBM SPSS Statistics 27.0.1	1.1.1f or later Note: Support for the insecure SSLv3 protocol has been deprecated.
   IBM SPSS Statistics 26-27	1.0.2 or later
   IBM SPSS Statistics 24-25	1.0.1f or later
   IBM SPSS Statistics 20-23	1.0.0
   IBM SPSS Statistics 17-19 (not Linux® on System z®)	0.9.8 and its subversions (0.9.8a, 0.9.8b, and so on)
   IBM SPSS Statistics 19 (Linux® on System z®)	1.0.0

2. Follow the instructions for installing and configuring the software. It is recommended to build OpenSSL yourself, with the following guidelines:

   Windows. OpenSSL should be built with DLLs (which are multithreaded by default).

   UNIX. OpenSSL should support multiple threads (which is not always by default) and shared libraries.

3. Make sure the OpenSSL modules are included on the system path.
   Note: If there is more than one version of the OpenSSL modules on the server computer, then copy the OpenSSL modules for the IBM SPSS Statistics Server to the directory where IBM SPSS Statistics Server is installed.
