[Need Help]: Qt5.15 support iOS TLS 1.3

[CellCS]

Now is using Qt5.15.19, and using

#if defined(Q_OS_IOS)
#if (QT_VERSION < QT_VERSION_CHECK(5, 15, 0))
    sslConfig.setProtocol(QSsl::TlsV1_2OrLater);
#else
    sslConfig.setProtocol(QSsl::TlsV1_3OrLater);
#endif
#elif defined(Q_OS_ANDROID)
    sslConfig.setProtocol(QSsl::TlsV1_3OrLater);
#endif

When when build by using Xcode and set mimi iOS as 13, get:

QTcpSocket(0x15c4c2430) SecureTransport does not support TLS 1.3
qt.network.ssl: QTcpSocket(0x15c4c2430) SecureTransport does not support TLS 1.3

Any suggestions? thanks a lot.

You could...

1. Install the OpenSSL development libraries
2. Rebuild the Qt libraries from source
3. Add the OpenSSL library folder to your project's DYLD_LIBRARY_PATH

See:

• General information about building Qt 5.15 from source code on macOS: https://doc.qt.io/qt-5/macos-building.html
• Instructions on how to make Qt Network use OpenSSL: https://doc.qt.io/qt-5/ssl.html#enabling-and-disabling-ssl-support

@JKSH

Thanks a lot. here is my current steps.

1. download qt source code.
2. .configure with using open-ssl linked.
3. make, make install
4. qt creator link this qt.
5. Xcode run, but meet some errors, even adding "QMAKE_CXXFLAGS += -DQML_DISABLE_JIT" in qtbase/mkspecs/common/ios.conf,

      JSC::Yarr::YarrPattern::digitsCharacterClass() in libQt5Qml.a[arm64][200](YarrPattern.o)

any suggestions? thanks a lot

Hi,

How exactly did you configure Qt ?
What kind of Mac are you using ? Intel or Apple Silicon ?

Thanks @SGaist @JKSH

issue of "JSC::Yarr::digitsCreate()" is fixed by python path.

Here is my env and steps:

Env: Apple M4 Pro, macOS: Sequoia 15.5.

Here are steps:

OpenSSL Lib prepare:
1-1: Download openssl-apple https://github.com/passepartoutvpn/openssl-apple?tab=readme-ov-file
1-2: ./build-libssl.sh --version=3.4.1 --targets="ios64-cross-arm64", and get "iphoneos18.5-arm64.sdk"

Download Qt source from Qt. (qt-everywhere-src-5.15.19)

Build Qt:
3-1: OPENSSL_LIBS='-L/Users/xxx/OpenSSL/iphoneos18.5-arm64.sdk/lib -lssl -lcrypto' ./configure
-xplatform macx-ios-clang
-release
-static
-nomake tests -nomake examples
-skip qtwebengine -skip qtscript -skip qtdoc -skip qtlocation
-openssl-linked
-I/Users/xxx/OpenSSL/iphoneos18.5-arm64.sdk/include
-L/Users/xxx/OpenSSL/iphoneos18.5-arm64.sdk/lib
-no-securetransport
-prefix /Users/xxx/Qt/5.15.19ios

3-2: make -j1
3-3: make install

4: Qt creator link this /Users/xxx/Qt/5.15.19ios/bin

5: build in Qt creator, run in Xcode

6. ❌🚧 Issue: "SSL handshake failed" when tries to communicate with one TLS1.3 api.

Any suggestions? thanks a lot.

If you build the Qt example app "Secure Socket Client Example" do you get the same error?

[CellCS]

Thanks @hskoglund @SGaist @JKSH

Now solved, and build qt can communicate with TLS 1.3 server.

After link with OpenSSL, need load cert files to support, system default one will be blank.

Cheers. thanks all!
