Hash Identifier
Identify hash types from their format - bcrypt, MD5, SHA, Argon2, and more
Password hashes often have distinctive prefixes like $2a$ (bcrypt),$argon2, or $6$ (SHA-512 crypt).
Raw cryptographic hashes are harder to distinguish since MD5, SHA-256, etc. produce similar-looking hex strings. The length is the main differentiator.
Context matters: A 32-character hex string could be MD5, NTLM, or MD4. Consider where the hash came from to narrow down possibilities.

Frequently Asked Questions
How accurate is hash identification?
Password hashes with unique prefixes (like bcrypt's $2a$) can be identified with high confidence. Plain hex hashes (MD5, SHA) are harder to distinguish since they look similar - the tool shows all possibilities with confidence scores.
Why are there multiple matches for my hash?
Many hash algorithms produce output of the same length. For example, MD5, NTLM, and MD4 all produce 32-character hex strings. Context about where the hash came from helps narrow it down.
Can this tool crack or reverse hashes?
No, this tool only identifies the hash type. Cryptographic hashes are one-way functions and cannot be reversed. For password hashes, the only way to verify is to hash the candidate password with the same algorithm and compare.
What do the confidence scores mean?
High confidence (80%+) means the hash matches a specific format with unique characteristics. Medium confidence (60-80%) means the format matches but could be multiple algorithms. Low confidence (<60%) means it's a possible match based on length alone.
