Compile YARA rules to test against files or strings

Project description

What’s in yara-ctypes:

  • A ctypes libyara wrapper module which exposes libyara’s exports into the Python runtime (see: yara-project’s libyara v1.7).

  • A thread safe Rules object with an interface that is compatible with the interface exposed in the yara-project CPython extension module.

  • namespace management to allow easy loading of multiple YARA rules into a single Rules matching object.

  • Various Scanner class types to enable thread or process pool execution of matching requests over a Rules object.

  • A feature rich command line interface that gives the user many options to control how they may wish to perform a scan.

Why:

  • ctypes releases the GIL on system function calls… Run your PC to its true potential.

  • It simplifies things a lot by keeping high order logic such as managing rules paths, filtering paths, controlling pooled execution, etc. inside of a language such as Python.

  • No more building the PyC extension…

  • I found a few bugs and memory leaks and wanted to make my life simple.
