6.2.4. RTI Secure WAN Transport

6.2.4.1. OpenSSL upgrade

Release 6.0.1 of Secure WAN Transport uses uses OpenSSL® 1.1.1d. (Release 5.3.1 used OpenSSL 1.0.2n, and Release 6.0.0 used OpenSSL 1.0.2o.) Secure WAN Transport 6.0.1 is API-compatible with OpenSSL versions 1.1.1a through 1.1.1d, not with OpenSSL 1.1.0 or below. If you need Secure WAN Transport 6.0.1 to run against older versions of OpenSSL, please contact support@rti.com.

Note

OpenSSL 1.0.2 will only be supported until the end of 2019 (https://www.openssl.org/policies/releasestrat.html), so it is recommended that you upgrade the version of OpenSSL that you are using to OpenSSL 1.1.1d for release 6.0.1. For instructions on installing the latest version of OpenSSL, see the RTI Secure WAN Installation Guide 6.0.1.

6.2.4.2. Changes to building an application

When building a Windows application, you must now link against libssl and libcrypto instead of ssleay32 and libeay32. When building a Windows statically-linked application, you must now link against the system library crypt32.lib. (See RTI Connext Core Libraries Platform Notes, for more information.)

When building a non-Windows statically-linked application, you may see this error:

undefined reference to 'pthread_atfork'

If so, open your makefile and make sure that -lpthread (which is part of $(SYSLIBS) in the makefile generated by RTI Code Generator) appears after -lssl and -lcrypto.
