# aesni

Simple AES encryption algorithm implementation using the AES-NI instruction
set.

## Building

I've used the compiler and the assembler shipped with Visual Studio Express
2013 with Update 4 for Windows Desktop.

You can generate the solution using CMake and build it using Visual Studio.

Some of the utilities also depend on a few Boost libraries.
In particular, Boost.Filesystem, Boost.Program_options, and Boost.System has to
be built prior to building these utilities.
To enable CMake to find Boost libraries, pass the path to the root Boost
directory like this:

    cmake -D BOOST_ROOT=C:\workspace\third-party\boost_1_58_0 ...

Remember that in order to link to the static Boost libraries, you also have to
pass `-D Boost_USE_STATIC_LIBS=ON` to CMake.

## Running on older CPUs

To run the executables that are using the AES-NI instruction set on a CPU w/o
the support for these instructions, one can use
[Intel Software Development Emulator](https://software.intel.com/en-us/articles/intel-software-development-emulator).
You can then run an executable like this:

    > sde -- encrypt_block.exe -a aes128 -m ecb -- 000102030405060708090a0b0c0d0e0f 00112233445566778899aabbccddeeff

## Documentation

You can generate the docs using
[Doxygen](http://www.stack.nl/~dimitri/doxygen/).
The docs will be put into the `doc` directory in the repository's root.
