What Is Hash Identifier?

The Hash Identifier recognizes hashes by shape: MD5, SHA-1 through SHA-512, bcrypt, Argon2, Django PBKDF2, MySQL password formats, and Unix crypt variants. Paste one hash per line to get every plausible algorithm, including the genuinely ambiguous cases like 32-hex MD5 versus NTLM.

Who Uses the Hash Identifier?

Developers, CTF players, and security analysts use it as the first step before choosing how to verify or audit a hash.

How to Use the Hash Identifier

  1. Paste one hash per line into the box.
  2. Read the identified algorithm beside each hash.
  3. Use the result to pick the right verification tool.

Why Choose Our Hash Identifier?

  • Covers modern, legacy, and framework formats
  • Honest about ambiguous lengths like MD5 vs NTLM
  • Multi-line batch identification
