Hash Identifier Online

Paste a hash value and get a list of possible algorithms based on its length, prefix and format. This is an educated guess, not a cryptographic analysis.

Hash string

Possible types

- bcrypt (high)
  Blowfish-based password hash. The number after the second $ is the cost factor (work factor).

How to Use

1.Paste the hash you want to identify.
2.Review the list of possible formats and confidence levels.
3.Use the result to pick the right cracking or verification tool.

FAQ

Can it identify plain SHA-256 hashes?

Raw SHA-256 hashes are 64 hex characters, but many algorithms share that length, so the confidence is lower without a prefix.

Is this tool safe for sensitive hashes?

Everything runs locally in your browser with JavaScript — nothing is uploaded, logged or stored. The hash is analysed locally and never sent to a server.
