This project provides an adaptation patch for the BoringSSL library, enabling its use in KasperskyOS-based solutions. The project is based on the 0.20250212.0 tag of the BoringSSL library.

For details on BoringSSL—a fork of the OpenSSL library—see its official README.md

For additional details on KasperskyOS, including its limitations and known issues, please refer to the KasperskyOS Community Edition Online Help.

1. Confirm that your host system meets all the System requirements listed in the KasperskyOS Community Edition Developer's Guide.
2. Install the KasperskyOS Community Edition SDK version 1.4. You can download it for free from os.kaspersky.com.
3. Copy the source files of this adaptation patch to your local project directory.
4. Source the SDK setup script to configure the build environment. This exports the KOSCEDIR environment variable, which points to the SDK installation directory:

   source /opt/KasperskyOS-Community-Edition-<platform>-<version>/common/set_env.sh

The KasperskyOS-adapted version of the BoringSSL library is built using the CMake build system, which is provided in the KasperskyOS Community Edition SDK. When you develop a KasperskyOS-based solution, use the recommended structure of project directories to simplify usage of CMake scripts.

To install the BoringSSL library adapted for KasperskyOS, run the following command:

$ cmake -B build -D CMAKE_TOOLCHAIN_FILE="$KOSCEDIR/toolchain/share/toolchain-aarch64-kos.cmake"
$ cmake --build build --target all
$ cmake --install build --prefix "$HOME/.local/share/kos/$(basename $KOSCEDIR)/sysroot-aarch64-kos"

To integrate the adapted BoringSSL library in a KasperskyOS-based solution, there are three recommended options: using the library source code as a git submodule, using the previously installed BoringSSL library, or using the CMake module FetchContent. For practical guidance, see the BoringSSL example in the KasperskyLab/kos-ce-extra repository, which demonstrates all three approaches.
