MD4 Hash Decrypt

The tool provides offline MD4 hash decryption via dictionary-based lookup. It accepts an MD4 hash and searches precomputed mappings to identify candidate plaintext strings. This is useful for security researchers analyzing legacy systems, incident responders tracing data provenance, and developers auditing data flows that rely on MD4 digests.
Conceptually, the workflow is input normalization, dictionary search, and result ranking. The engine does not perform on-the-fly cryptanalysis or exploit MD4 weaknesses; it relies on offline dictionaries to associate plaintexts with their digests.
Benefits include deterministic results, fast response times, and zero network dependency. It supports multiple dictionaries, encoding variants, and an escape hatch for custom wordlists. Use cases include verifying data migrations, analyzing logs with MD4 references, and reproducible security audits.
Distinctive value lies in its offline design, strict focus on MD4, and clear output of candidate plaintexts with confidence scores. It is suitable for environments that require auditable hash-to-plaintext mapping without live cracking.
