afl-cmin(1) corpus minimization tool for American Fuzzy Lop (afl)


afl-cmin [options] -- /path/to/fuzzed/app [params]


afl-cmin tries to find the smallest subset of files in the input directory that still trigger the full range of instrumentation data points seen in the starting corpus.

If a large corpus of data is available for screening, afl-cmin can be used to reject redundant files, ideally, with an aggressive timeout (set by -t).

Note that the tool doesn't modify the files themselves. For that, you want afl-tmin.


Run afl-cmin without any arguments to see a complete list of options.
