Hash Type Identifier
Possible types
Identification is a best guess based on length and format, not a certainty.
What is Hash Type Identifier
A hash identifier looks at a hash string and tells you which algorithms could have produced it. It matches the length and character set (and any prefix like $2b$ for bcrypt or $6$ for SHA-512 crypt) against known formats and lists the likely candidates. Because different algorithms can share the same length, it gives a ranked best guess rather than a single certain answer. It runs entirely in your browser.
How to use
- Paste the hash you want to identify.
- Read the list of possible hash types, most likely first.
- Use the prefix or context (where the hash came from) to narrow it down.
- Copy the link to share the hash and its detected types.
When to use it
Pulled an unknown hash from a database dump or a CTF challenge and need to know what it is before cracking it? Paste it here: a 32-character hex string comes back as MD5 or NTLM, while '$2b$...' is flagged as bcrypt right away. It is a quick first step before reaching for a wordlist or picking the right generator to compare against.
Frequently asked questions
Can it tell me the exact algorithm for sure?
No. Many algorithms produce the same output length, so a 64-character hex hash could be SHA-256, SHA3-256, or others. The tool ranks the most likely types, but context from where the hash came is what confirms it.
Does it crack or reverse the hash?
No. Hashes are one-way, so there is nothing to reverse. This tool only identifies the likely type. To check a password against a hash, generate the hash of your guess and compare.
Which formats does it recognise?
Common hex hashes (MD5, SHA-1, SHA-224/256/384/512, SHA-3, RIPEMD, BLAKE2, Whirlpool, CRC) plus prefixed formats like bcrypt, Argon2, phpass, MySQL, and Unix crypt (md5crypt, sha256crypt, sha512crypt).
Can I share this with my hash pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Copy link button, and anyone who opens it sees the same hash and its detected types.
