About Hash Identifier

Work out which algorithm produced a hash you found in a database dump, a config file or a log, using its length, character set and prefix.

Key Features

Recognizes 35 prefixed formats outright, including bcrypt, Argon2, yescrypt, SHA-512-crypt, Apache APR1, phpass, Django, LDAP SSHA, MSSQL and MySQL
Ranks candidates for ambiguous raw digests by length, covering CRC-32 through SHA-512, and flags Base64-encoded digests by their decoded byte count
Labels each match as a slow password hash, a fast unsalted digest, or a plain checksum, so you know whether you are looking at a credential at all

Use Cases

Identify the hashing scheme in a legacy database before planning a migration to bcrypt or Argon2
Sort a mixed credential dump into formats during an authorized penetration test or a CTF challenge
Confirm whether a value in a config file is a password hash, an API checksum, or a JWT that should be decoded instead

Why some hashes can never be told apart

A raw digest carries no metadata, so any two algorithms with the same output size look identical. MD5, NTLM, MD4 and LM are all 32 hex characters; SHA-256, SHA3-256 and BLAKE2s-256 are all 64. Where the value came from is the real evidence: a Windows ntds.dit dump means NTLM, a WordPress users table means phpass or bcrypt, an /etc/shadow line is named by its own prefix. Formats that start with a $ are unambiguous because the algorithm, cost and salt are stored right there in the string.

Nothing is uploaded or cracked

Identification is pure pattern matching in your browser: no hash is sent anywhere, looked up in a rainbow table, or stored. This tool names the format, it does not attempt to recover the original value.
