Hash Identifier
Identify the likely type of a hash from its format.

Identification is based on length and format, so more than one type can match. It is a hint, not a guarantee.
Everything runs in your browser and the hash is never uploaded.
About the Hash Identifier
Identify the likely type of a hash from its length and format, such as MD5, SHA-1, SHA-256, SHA-512 or bcrypt.
Paste a hash and get a list of matching formats to help you decide how it was made.
Because several hashes share the same length, results are hints rather than certainties.
Key features
- Detects common hex hashes by length
- Recognizes bcrypt, Argon2 and Unix crypt prefixes
- Shows all matching formats
- Runs entirely in your browser
How to use
- 1Paste the hash you want to identify.
- 2Read the list of likely hash types.
- 3Use the format prefixes to narrow it down.
Examples
MD5 length
Input:
5d41402abc4b2a76b9719d911017c592Output:
MD5 or NTLMA 32-character hex string matches these types.
bcrypt prefix
Input:
$2b$10$...Output:
bcryptThe $2 prefix identifies a bcrypt hash.
Frequently asked questions
- Why do I get more than one result?
- Different hashes can share the same length, so a 32-character hex string could be MD5 or NTLM, for example.
- Can it reverse a hash?
- No. Hashing is one-way. This tool only guesses the type; it cannot recover the original input.
- Is my hash uploaded?
- No. Identification runs entirely in your browser.
