Password Security 101: Entropy, Hashing Algorithms, and Salt Protection

# Password Security 101: Entropy, Hashing Algorithms, and Salt Protection Password security relies on password length, character pool diversity, and strong cryptographic hashing algorithms. ## Calculating Password Entropy Entropy measures password randomness in bits. A 12-character password mixing uppercase, lowercase, numbers, and symbols provides over 70 bits of entropy, requiring trillions of compute years to crack via brute force.
