* Reorganize crypto/aes in order to separate parameters, implementations and modes. * Add a zero-cost abstraction over the internal representation of a block, so that blocks can be kept in vector registers in optimized implementations. * Add architecture-independent aesenc/aesdec/aesenclast/aesdeclast operations, so that any AES-based primitive can be implemented, including these that don't use the original key schedule (AES-PRF, AEGIS, MeowHash...) * Add support for parallelization/wide blocks to take advantage of hardware implementations. * Align T-tables to cache lines in the software implementations to slightly reduce side channels. * Add an optimized implementation for modern Intel CPUs with AES-NI. * Add new tests (AES256 key expansion). * Reimplement the counter mode to work with any block cipher, any endianness and to take advantage of wide blocks. * Add benchmarks for AES.
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

Building from Source
Note that you can download a binary of master branch or install Zig from a package manager.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
Need help? Troubleshooting Build Issues
MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue:
homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
This has been fixed upstream with LLVM 10.0.1.
Building with LLVM 10.0.1 you might run into this problem:
ld: library not found for -llibxml2.tbd
Building with LLVM 10.0.1 installed via Homebrew fails,
in which case you can try -DZIG_WORKAROUND_6087=ON.
Windows

License
The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better code. Even more important, however, are the end users.
Zig is intended to be used to help end users accomplish their goals. For example, it would be inappropriate and offensive to use Zig to implement dark patterns and it would be shameful to utilize Zig to exploit people instead of benefit them.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides to users.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end users.
