Hash Identifier
Identify probable hash algorithm types (MD5, SHA-1, SHA-256, SHA-512, bcrypt) by string length.
About Hash Identifier
The Cryptographic Hash Identifier analyzes unknown hash strings and detects potential algorithm families (MD5, SHA-1, SHA-256, SHA-512, bcrypt, Argon2, NTLM, CRC32) based on character length, encoding pattern, and salt format.
How to Use Hash Identifier
Step 1
Paste your unknown hash string into the analyzer.
Step 2
View probable matching hash algorithms ranked by confidence.
Step 3
Inspect bit length, character set, and format standards.
Practical Use Cases for Hash Identifier
Cybersecurity & Incident Response Analysis
Identify unknown password hashes and database dump signatures during security vulnerability audits and penetration tests.
Software Forensic Verification
Determine the hash algorithm used in legacy application databases and configuration manifests.

Key Terminology & Definitions
Modular Crypt Format (MCF)
A standard string format for password hashes containing algorithm identifiers, cost parameters, salt, and hash separated by dollar signs ($).
Hash Length & Bit Depth
The fixed output size of a hash function (e.g. 32 hex chars = 128 bits, 64 hex chars = 256 bits).
