Algorithms

MemDiver ships 8 detection algorithms, discovered automatically by algorithms.registry. One requires ground-truth secrets (known_key); seven do not (unknown_key).

Algorithm	Mode	Purpose
`exact_match`	`known_key`	Literal byte-search for known-secret sequences using `context.secrets`.
`entropy_scan`	`unknown_key`	Sliding-window Shannon entropy above a threshold.
`change_point`	`unknown_key`	CUSUM-based entropy-plateau detection.
`differential`	`unknown_key`	DPA-inspired cross-run byte variance.
`constraint_validator`	`unknown_key`	TLS KDF relationship verification for candidates.
`user_regex`	`unknown_key`	Custom regex patterns.
`pattern_match`	`unknown_key`	Structural matching from JSON pattern definitions.
`structure_scan`	`unknown_key`	Structure-library-backed overlay + best-match scoring.

Contracts

All algorithms share the same interface from algorithms.base:

class BaseAlgorithm:
    name: str
    description: str
    mode: str

    def run(self, dump_data: bytes, context: AnalysisContext) -> AlgorithmResult: ...
