SYNOPSISafl-analyze [options] -- /path/to/target_app [...]
DESCRIPTIONafl-analyze takes an input file, attempts to sequentially flip bytes, and observes the behavior of the tested program. It then color-codes the input based on which sections appear to be critical, and which are not. While not bulletproof, it can often offer quick insights into complex file formats.
