I want to use QSslSocket and QSslCertificate with my latest OpenSSL build. I built OpenSSL 1.1.0 with VS2015 and added its bin directory into %PATH , also added its LIBS to my .pro file: LIBS += -LC:/openssl_1.1.0/lib/ -llibcrypto -llibssl When I run my application, QSslSocket::supportsSsl() returns false and QSslSocket::sslLibraryBuildVersionString() returns OpenSSL 1.0.2g 1 Mar 2016 , even though I built OpenSSL 1.1.0. Also I get error messages like this: qt.network.ssl: QSslSocket: cannot call unresolved function SSLv23_client_method qt.network.ssl: QSslSocket: cannot call unresolved function SSL_CTX_new qt.network.ssl: QSslSocket: cannot call unresolved function SSL_library_init qt.network.ssl: QSslSocket: cannot call unresolved function ERR_get_error What is the problem? How can I use my built OpenSSL libraries and binaries? P.S. I use Windows 10, Qt 5.7, OpenSSL 1.1.0, Visual Studio 2015 Enterprise. Thank you

Hi and welcome to devnet, Don't copy .dlls like that in the Windows folder, that's very bad practice. If Qt shows you a different version of OpenSSL, it likely means that you have an application that also provides these files and can be found before yours. I've successfully used the prebuilt packages from Shining Lights Production . Hope it helps

IIRC there was a renaming of the libraries of OpenSSL so you'll have to double check.
