Hello,

I'm new to the OPC UA world. Could someone please help me with replacing OpenSSL v1.1.1.13 (uasdkcppbundlepubsub-src-win32-x86-vs2015-v1.7.5-534.exe)? What is the sequence I need to follow to rebuild the project with OpenSSL v3.5.x? OpenSSL v1.1.1.13 will be phased out by January 2026. What is the best approach? Is there compatibility between the UA SDK version and OpenSSL?

I tried replacing \third_party\openssl\include and \third_party\openssl\lib with v3.5.4, but the build is broken.

I appreciate any help.

The uasdkcppbundlepubsubis not a package distributed by the OPC-F

You should look in the readmes to figure out the correct vendor.

Hello Hannah,

your SDK appears to be the C++ SDK of Unified Automation which is one of the Members of the OPC Foundation and active in many working groups. Please find their contact information on their website, I'm sure they can help with the OpenSSL Update:
