Why Strong Passwords Matter
Modern GPU hardware can test billions of password combinations per second. A short, simple password can be cracked in seconds. Strong passwords of 16+ characters with mixed case, numbers, and symbols would take millions of years to brute-force.
Understanding Hash Functions
Hash functions convert any input into a fixed-length string of characters. They are one-way (you cannot reverse a hash to get the original input), deterministic (same input always produces the same hash), and collision-resistant (different inputs produce different hashes). Common algorithms include MD5, SHA-1, SHA-256, and bcrypt.
Password Storage Best Practices
Never store passwords in plain text. Use bcrypt, scrypt, or Argon2 for password hashing — these algorithms are intentionally slow, making brute-force attacks impractical. MD5 and SHA-256 are fast hash functions designed for data integrity, not password storage.
