How to use

  1. Open the tool and paste your input into the left pane.
  2. Set only the options your task actually needs — the defaults are correct for most inputs.
  3. Read the result in the right pane; it updates as you type.
  4. Use Copy to take the result, or Download to save it as a file.

Examples

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

Output — Results

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.

Run

Description

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