Argon2

A multi-arch library implementing the Argon2 password hashing algorithm.

This project is based on the original source code by the Argon2 authors. The goal of this project is to provide efficient Argon2 implementations for various HW architectures (x86, SSE, ARM, PowerPC, ...).

For the x86_64 architecture, the library implements a simple CPU dispatch which automatically selects the best implementation based on CPU flags and quick benchmarks.

Building

Using GNU autotools

To prepare the build environment, run:

autoreconf -i
./configure

After that, just run make to build the library.

Running tests

After configuring the build environment, run make check to run the tests.

Architecture options

You can specify the target architecture by passing the --host=... flag to ./configure.

Supported architectures:

• x86_64 – 64-bit x86 architecture
• generic – use generic C impementation

Using CMake

To prepare the build environment, run:

cmake -DCMAKE_BUILD_TYPE=Release .

Then you can run make to build the library.

Using QMake/Qt Creator

A QMake project is also available in the qmake directory. You can open it in the Qt Creator IDE or build it from terminal:

cd qmake
# see table below for the list of possible ARCH and CONFIG values
qmake -recursive ARCH=... CONFIG+=...
make

Architecture options

For QMake builds you can configure support for different architectures. Use the ARCH variable to choose the architecture and the CONFIG variable to set additional options.

Supported architectures:

• x86_64 – 64-bit x86 architecture
  • QMake config flags:
    • USE_SSE2 – use SSE2 instructions
    • USE_SSSE3 – use SSSE3 instructions
    • USE_XOP – use XOP instructions
    • USE_AVX2 – use AVX2 instructions
    • USE_AVX512F – use AVX-512F instructions
• generic – use generic C impementation
