What it does

The

HashHashA one-way function that maps data of any size to a fixed-length digest. Same input, same digest; any change, different digest; not reversible.

Type Identifier inspects a hash string’s length and character set to rank the algorithms that could have produced it - MD5, SHA-1/2/3, BLAKE, CRC32, NTLM, bcrypt, Argon2, and more. Several algorithms share output lengths, so the tool lists every plausible candidate in a ranked list instead of guessing one. 100% client-side.

How to use it

1. Paste a

   hashhashA one-way function that maps data of any size to a fixed-length digest. Same input, same digest; any change, different digest; not reversible.

   into

   (or tap a Try: chip - each chip is a real digest of the string cosmolabs).
2. Read the Length, Charset, and Bit length stats, then the ranked Likely algorithms list. The #1 row is the most common algorithm for that shape.
3. Copy report copies the ranked list as plain text, and the

MD5 - 32 hex chars

60b4749f2e2b300800ee2b5548172316 → MD5, MD4, NTLM, LM, MD2, RIPEMD-128, HAVAL-128 (all 128-bit).

SHA-256 - 64 hex chars

88576c6aa610e5867476f52922d1a138860e8eacc2bbe18a16dc124da7b77139 → SHA-256, SHA3-256, BLAKE2s-256, RIPEMD-256, Skein-256 (all 256-bit).

SHA-1 - 40 hex chars

006ce81575e12e1be321224f6ce62e758b6bd4bf → SHA-1, RIPEMD-160, HAVAL-160, MySQL 5.x (SHA1(SHA1)), Tiger-160.

CRC32 - 8 hex chars

5e86ed79 → CRC32, Adler-32.

Good to know

• Heuristic only: length and charset are clues, not proof. Every 64-hex digest could be SHA-256 or SHA3-256 - only re-

  a known input can tell them apart.
• bcrypt and Argon2 carry their own format ($2…$, $argon2…$), so they are matched by prefix rather than length.
