MD4 hash

Client

Compute MD4 hex for legacy Windows NTLM or old protocol compatibility—modern systems should prefer SHA-256.

About MD4 hash

Legacy MD4 digest (hex) for interoperability checks—do not use for new security. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.

Limits and safety

Utilities here are for development and inspection—do not paste live production keys, PANs, or recovery codes into any browser tab you do not control.

Nearby workflows on Toolcore

  • Hash identifier — Guess digest type from hex length, Base64 shape, or bcrypt/Argon2 prefixes—heuristic, local only. before you trust a token, digest, or key material in production.
  • CRC-32 & CRC-32C — IEEE CRC-32 and Castagnoli CRC32C on UTF-8 text or raw hex bytes—ZIP/PNG family vs iSCSI/protobuf; local only, complements file checksum for whole-file digests. before you trust a token, digest, or key material in production.
  • HMAC (SHA-256 & more) — HMAC-SHA-256/384/512/1 in the browser—hex or Base64 for webhooks, signing, and API docs. before you trust a token, digest, or key material in production.
  • Bcrypt hash & verify — bcrypt password digests with adjustable cost (bcryptjs)—hash or verify $2a/$2b strings locally. before you trust a token, digest, or key material in production.

Common use cases

  • MD4 hash for quick local checks without uploading data.
  • Copy results into tickets, docs, or classroom notes.
