differential

Mode: unknown_key  ·  File: algorithms/unknown_key/differential.py

Byte-level variance across ≥2 dumps, DPA-inspired. Regions whose byte values change between runs but whose length matches a target key size (32, 48) are candidate keys.

Parameters (read from context.extra)

Key	Default
dump_paths: List[Path]	required, ≥2

Class constants: TARGET_KEY_LENGTHS = [32, 48], LENGTH_TOLERANCE = 8, MAX_GAP_BYTES = 4.

Output

Match.label = "diff_key_candidate_{N}B". Requires at least 2 dump paths or the algorithm returns confidence 0.
