Hash Identifier & Generator
Identify unknown hash types by length and format, or generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text. Essential for password cracking prep and data integrity checks.
What is Hash Identification?
Hash identification is a critical skill for security professionals working with password dumps, digital forensics, or CTF challenges. Different hash algorithms produce different output lengths and character patterns — MD5 produces 32 hex characters, SHA-256 produces 64, and bcrypt has a distinctive "$2y$" prefix. This free hash identifier and generator helps you quickly identify and create common cryptographic hashes.
