Android OpenSSL support for Qt

OpenSSL scripts and binaries for Android (useful for Qt Android apps)

In this repo you can find the prebuilt OpenSSL libs for Android, a QMake include project .pri file that can be used integrated with Qt projects, and a .cmake file for CMake based projects.

The following directories are available

• ssl_3: used for Qt 6.5.0+.
• ssl_1_1: for Qt Qt 5.12.5+, 5.13.1+, 5.14.0+, 5.15.0+, Qt 6.x.x up to 6.4.x

How to use it

QMake based projects

To add OpenSSL to your QMake project, append the following to your .pro project file:

android: include(<path/to/android_openssl/openssl.pri)

CMake based projects

To add OpenSSL to your CMake project, append the following to your project's CMakeLists.txt file:

if (ANDROID)
    FetchContent_Declare(
      android_openssl
      DOWNLOAD_EXTRACT_TIMESTAMP true
      URL      https://github.com/KDAB/android_openssl/archive/refs/heads/master.zip
#      URL_HASH MD5=c97d6ad774fab16be63b0ab40f78d945 #optional
    )
    FetchContent_MakeAvailable(android_openssl)
    include(${android_openssl_SOURCE_DIR}/android_openssl.cmake)
endif()

or, if you cloned the repository into a subdirectory:

include(<path/to/android_openssl>/android_openssl.cmake)

Then

qt_add_executable(your_target_name ..)
qt_add_executable(your_second_target_name ..)

if (ANDROID)
    add_android_openssl_libraries(your_target_name your_second_target_name)
endif()

Build Script

The build script build_ssl.sh can be used to rebuild the OpenSSL libraries. Since specific versions might depend or work better with specific NDK versions, the OpenSSL<==>NDK version combinations are defined in the script. Before running the script, check that the NDK paths are correct for your environment.

Build Prerequisites

Both Linux, macOS need patchelf command when building for OpenSSL 3+.

Additionally, for macOS you need:

• bash shell version 4+ is required
• wget command
