Hash Identifier

No. Identification runs entirely in your browser using JavaScript, so the hash you paste never leaves your device. That matters when a hash comes from a password database or another sensitive source.

It is purely heuristic. The tool first looks for known prefixes such as $2y$ for bcrypt, $6$ for SHA-512 crypt, or {SSHA} for LDAP. If none match and the string is all hexadecimal, it maps the length to a list of algorithms that produce that many characters.

Only for prefixed formats like bcrypt, Argon2, or Unix crypt, where the leading characters uniquely name the scheme. For a plain hex string it can only rank possibilities, because length and character set do not uniquely identify the algorithm.

Not from the hash alone. Both are 32 hexadecimal characters, so they are indistinguishable by format. The tool ranks MD5 as high because it is far more common and lists NTLM as a medium-confidence alternative for you to consider.

Many algorithms share an output length. A 64-character hex string could be SHA-256, SHA3-256, or BLAKE2s-256, so the tool shows every plausible match ordered by likelihood rather than guessing a single answer.

That means the string did not match a known prefix and its length and character set did not line up with a common raw hash. Salted formats, base64 output, truncated hashes, or extra whitespace can all cause this. Trim the value and paste just the hash.

Partly. It recognizes several salted formats that carry a standard prefix, such as bcrypt, Unix crypt, and LDAP SSHA. A raw hash with a separate salt, or one encoded as base64 rather than hex, will often come back as Unknown.

No. Cryptographic hashes are one-way, so knowing the algorithm only tells you how a value was produced, not the original input. Recovering the input still requires guessing candidates and hashing them, which is what password cracking tools do.

No, it analyzes one hash at a time. Paste a single value; multiple lines or a labeled entry will usually fail to match. For bulk work, feed the algorithm guess into a dedicated tool like hashcat or John the Ripper.
