Examples

The SHA-256 of "abc" — 64 hex characters narrows it to SHA-256, SHA3-256 or BLAKE2s.

Input

ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad

Output

Input: ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
Length: 64 characters
Encoding: hexadecimal → 256 bits (32 bytes)
Encoding: Base64 → ~384 bits (48 bytes)
Encoding: Base64url → ~384 bits (48 bytes)

Likely algorithm(s) — 1 candidate(s):
  • SHA-256 / SHA3-256 / BLAKE2s

Note: identification is by length and character set only. Several algorithms share a
digest size (SHA-256, SHA3-256 and BLAKE2s all produce 64 hex characters), so this
can narrow the field but cannot prove which one was used.

This output was produced by actually running the tool, not written by hand.

Use cases

Common situations where Hash Type Identifier helps:

  • Guess which algorithm produced a hash from its length, encoding and character set.

Parameters

This tool has no options — it works on the input alone.

FAQ

What is Hash Type Identifier?

Hash Type Identifier guess which algorithm produced a hash from its length, encoding and character set. It runs entirely in your browser, so your data stays private.

Is Hash Type Identifier free to use?

Yes. Hash Type Identifier is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
