How Hash Identification Works
- • Length Analysis: Different algorithms produce different output lengths
- • Format Recognition: Structured hashes (bcrypt, Argon2, PBKDF2) have distinctive formats
- • Pattern Matching: Character patterns help distinguish between algorithms
- • Confidence Levels: Higher confidence when format is unique to one algorithm
- • Multiple Matches: Some lengths match multiple algorithms (disambiguation needed)
- • PBKDF2 Detection: Identifies both raw output and structured formats
Supported Hash Types (100+)
Cryptographic Hashes:
- • MD2, MD4, MD5 (deprecated)
- • SHA-1 (deprecated)
- • SHA-224, SHA-256, SHA-384, SHA-512
- • SHA-3 / Keccak variants
- • BLAKE2b, BLAKE2s, BLAKE3
- • RIPEMD-160
- • Whirlpool, Tiger-192
- • GOST R 34.11-94, HAVAL, Snefru
Password Hashes:
- • bcrypt ($2a$, $2b$, $2y$)
- • Argon2 (id, d, i variants)
- • scrypt, yescrypt
- • PBKDF2 (structured & raw)
- • HMAC-SHA1/256/512
- • Unix Crypt (DES, MD5, SHA-256/512)
- • Apache MD5 (APR1)
Database Hashes:
- • MySQL 3.x, 4.1/5.x
- • PostgreSQL MD5
- • Oracle 10g, 11g, 12c
- • MSSQL 2000, 2005, 2012+
- • MongoDB ScramSHA1/256
CMS/Frameworks:
- • WordPress ($P$, $H$)
- • Drupal 7+ ($S$)
- • Joomla (bcrypt, MD5+salt)
- • phpBB3 ($H$)
- • vBulletin (3.8.5+, older)
- • Django (PBKDF2, bcrypt)
Windows/Network:
- • LM Hash (deprecated)
- • NTLM, NTLMv2
- • Domain Cached Credentials (DCC/DCC2)
- • Cisco Type 5, 7, 9
- • Cisco IOS SHA256
- • Juniper NetScreen
LDAP/Other:
- • LDAP SSHA, SSHA256, SSHA512
- • LDAP MD5, SHA, Crypt
- • Base64-encoded hashes
- • CRC32, Adler-32 (checksums)
Important Notes
- • Raw Hash Limitation: Cannot distinguish between algorithms with same output length
- • Deprecated Algorithms: MD5 and SHA-1 are cryptographically broken - avoid for new systems
- • PBKDF2 Raw Output: Looks identical to SHA-256, SHA-512, BLAKE variants, etc.
- • Context Matters: Use application context, file extensions, or documentation to confirm identification
- • Verification Method: Try PBKDF2 verification with known parameters to confirm
- • Modern Systems: If hash is from recent application, prefer modern algorithms over legacy ones
- • Security: Never attempt to reverse or crack hashes without proper authorization
