Secure password hashing functions such as Bcrypt and Argon2 are specifically designed to be slow. [35] This slowness, combined with a unique "salt" for each hash, makes it extremely difficult and time-consuming for attackers to crack passwords via brute-force or rainbow table attacks. [34, 39] PHP provides the built-in functions password_hash() and password_verify() for this purpose. [31, 32]
Standard hashing algorithms (such as SHA-256) are designed for speed. [38] They are perfect for verifying file integrity or generating unique IDs, but their speed makes them unsuitable for securing passwords. [24] A fast hash can be guessed billions of times per second on modern hardware, making passwords vulnerable.
