Hash Algorithm Guide
You cannot reverse a hash to find the original password. Hash functions are designed to be irreversible. The "Verify Hash" feature works by hashing your password again and comparing the results - not by reversing the hash.
Step 1: User creates password → System hashes it → Stores hash in database
Step 2: User logs in → System hashes entered password
Step 3: System compares stored hash vs. new hash
Result: If hashes match = correct password! No passwords stored in plain text.
Rainbow Tables: Pre-computed hash databases for common passwords
Brute Force: Trying millions of password combinations
Dictionary Attacks: Testing common passwords systematically
Protection: Use bcrypt/Argon2 with salt to prevent these attacks!
Designed specifically for password hashing with adaptive cost. Includes built-in salt and is resistant to rainbow table attacks.
Winner of the Password Hashing Competition. Provides excellent protection against both side-channel and GPU attacks.
Fast and secure for file integrity checks, but requires additional salting for password storage.
Cryptographically broken or vulnerable. Only use for compatibility with legacy systems.
