fuzzing-dictionary

separate

Builds and applies fuzzing dictionaries so a fuzzer can produce the keywords, magic bytes, and tokens a target expects. Covers extracting tokens from source, headers, binaries, and specifications, dictionary syntax, and wiring one into libFuzzer or AFL++. Use when fuzzing a parser, protocol, or file format, when coverage stalls at input validation, or when a target compares against fixed strings.

When to use

• Fuzzing parsers
• Fuzzing protocol implementations
• Fuzzing file format handlers
• Coverage plateaus early
• Target code checks for specific keywords
• Extracting tokens from source
• Extracting tokens from headers
• Extracting tokens from binaries

When not to use

• Fuzzing pure algorithms without format expectations
• Target has no keyword-based parsing
• Corpus already achieves high coverage
