Hash identification analyzes hash length and character set to determine algorithm (MD5, SHA-1, SHA-256, etc.). Essential for security analysis, password cracking, and forensics.
💡
Pro Tips
MD5: 32 hex characters (128 bits).
SHA-1: 40 hex characters (160 bits).
SHA-256: 64 hex characters (256 bits).
bcrypt: starts with $2a$, $2b$, or $2y$.

Fun Facts
"MD5 considered broken for security (collision attacks)."
"SHA-256 used in Bitcoin mining."
"Hash functions are one-way (cannot reverse)."
"Salt prevents rainbow table attacks."
Formula: Identify by length: MD5=32, SHA-1=40, SHA-256=64 hex chars
