+libfido2 can be fuzzed using AFL or libFuzzer, with or without
+ASAN/MSAN/UBSAN.
+
+AFL is more convenient when fuzzing the path from the authenticator to
+libfido2 in an existing application. To do so, use preload-snoop.c with a real
+authenticator to obtain an initial corpus, rebuild libfido2 with -DFUZZ=ON, and
+use preload-fuzz.c to read device data from stdin.
+
+libFuzzer is better suited for bespoke fuzzers; see fuzz_cred.c, fuzz_credman.c,
+fuzz_assert.c, fuzz_hid.c, and fuzz_mgmt.c for examples. To build these
+harnesses, use -DFUZZ=ON -DLIBFUZZER=ON.
+
+If -DFUZZ=ON is enabled, symbols listed in wrapped.sym are wrapped in the
+resulting shared object. The wrapper functions simulate failure according to a
+deterministic RNG and probabilities defined in wrap.c. Harnesses wishing to
+use this functionality should call prng_init() with a seed obtained from the
+corpus. To mutate only the seed part of a libFuzzer harness's corpora,
+use '-reduce_inputs=0 --fido-mutate=seed'.
+
+To run under ASAN/MSAN/UBSAN, libfido2 needs to be linked against flavours of
+libcbor and OpenSSL built with the respective sanitiser. In order to keep
+memory utilisation at a manageable level, you can either enforce limits at
+the OS level (e.g. cgroups on Linux), or patch libcbor with the diff below.
