Hash Identifier
// Identify hash algorithms from hash strings
Hash Input
Paste a hash above to identify its algorithm.
Supports MD5, SHA-1, SHA-256, SHA-384, SHA-512, bcrypt, Argon2, scrypt, CRC32, NTLM, and more.
#About Hash Identifier
Free online hash identifier. Paste a hash string and identify the likely algorithm — MD5, SHA-1, SHA-256, SHA-512, bcrypt, argon2, and more. This tool runs entirely in your browser — your data is never sent to a server. Just paste your input, get instant results, and copy with one click. No sign-up or installation required.
#FAQ
How does hash identification work? ▾
The tool analyzes the hash length, character set, and format prefix to determine likely algorithms. For example, 32 hex characters suggests MD5, 64 hex characters suggests SHA-256, and $2b$ prefix indicates bcrypt.
Can it identify the exact algorithm? ▾
Some hashes have unique prefixes (like bcrypt or argon2) that allow exact identification. For others like MD5 and NTLM that share the same length, the tool lists all possible matches with confidence levels.
