Hash Algorithm Guide
You cannot reverse a hash to find the original password. Hash functions are designed to be irreversible. The verify 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.
Winner of the Password Hashing Competition. Provides excellent protection against both side-channel and GPU attacks. The recommended choice for new applications requiring secure password storage.
Designed specifically for password hashing with adaptive cost factor. Includes built-in salt generation and is resistant to rainbow table attacks. Industry standard for password storage.
Fast and secure for file integrity checks, digital signatures, and data verification. Requires additional salting mechanism if used for password storage.
Cryptographically broken or vulnerable to collision attacks. Only use for compatibility with legacy systems that cannot be updated. Never use for new security implementations.
