Fuzzers

This directory contains a collection of fuzzing tools. Each tests a different entry point to the code.

Usage notes:

  1. Install AFL:

    apt-get install afl

  2. Build the fuzzers:

    make fuzzers

  3. Some of the tests (eg fuzz_decrypt and fuzz_group_decrypt) require a session file. You can use the ones generated by the python test script (python/test.sh).

  4. Make some work directories:

    mkdir -p fuzzing/in fuzzing/out

  5. Generate starting input:

    echo "Test" > fuzzing/in/test

  6. Run the test under afl-fuzz:

    afl-fuzz -i fuzzing/in -o fuzzing/out -- \
   ./build/fuzzers/fuzz_<fuzzing_tool> [<test args>]

  7. To resume with the data produced by an earlier run:

    afl-fuzz -i- -o existing_output_dir [...etc...]

  8. If it shows failures, pipe the failure case into ./build/fuzzers/debug_<fuzzing_tool>, fix, and repeat.
