Notice: This project is discontinued and no longer maintained nor supported by Tresorit. This repository only exists for archival purposes.

This library provides native cryptographic primitives for ZeroKit clients, utilizing OpenSSL's platform-specific optimized assembly implementations where possible. Currently supported platforms are iOS (arm, arm64, x86, x64) and Android (arm, arm64, x86).

• git
• GNU make
• Perl 5
• Android NDK (Android)
• Xcode (iOS)

Clone the repository and its submodules: git clone https://github.com/tresorit/ZeroKit-Client-Native-Crypto.git --recursive

Generate toolchains for the desired platforms:

 $ cd /path/to/ndk/
 $ build/tools/make_standalone_toolchain.py --arch arm --api 14 --stl libc++ --install-dir /path/to/toolchain/tc-arm
 $ build/tools/make_standalone_toolchain.py --arch arm64 --api 21 --stl libc++ --install-dir /path/to/toolchain/tc-arm64
 $ build/tools/make_standalone_toolchain.py --arch x86 --api 14 --stl libc++ --install-dir /path/to/toolchain/tc-x86

The library can be built for multiple platforms from the same source dir by specifying multiple out dirs. The result will be libZeroKitClientNative.so (the stripped, dynamically linked library) and libZeroKitClientNative.so.debug (the debug symbols for the library) in every out dir.

 $ cd /path/to/zerokitclientnative/
 $ make TARGET_OS=android TARGET_CPU=arm ANDROID_TOOLCHAIN_PATH_ARM=/path/to/toolchain/tc-arm OUTDIR=out/arm -j5
 $ make TARGET_OS=android TARGET_CPU=arm64 ANDROID_TOOLCHAIN_PATH_ARM64=/path/to/toolchain/tc-arm64 OUTDIR=out/arm64 -j5
 $ make TARGET_OS=android TARGET_CPU=x86 ANDROID_TOOLCHAIN_PATH_X86=/path/to/toolchain/tc-x86 OUTDIR=out/x86 -j5

The library can be built for multiple platforms from the same source dir by specifying multiple out dirs. The result will be libZeroKitClientNative.a (statically linked archive of the required object files) in every out dir.

 $ cd /path/to/zerokitclientnative/
 $ make TARGET_OS=ios TARGET_CPU=arm OUTDIR=out/arm -j5
 $ make TARGET_OS=ios TARGET_CPU=arm64 OUTDIR=out/arm64 -j5
 $ make TARGET_OS=ios TARGET_CPU=x86 OUTDIR=out/x86 -j5
 $ make TARGET_OS=ios TARGET_CPU=x64 OUTDIR=out/x64 -j5
