bcrypt

Passwords should never be encrypted for later recovery. I store slow one-way hashes, tune work factors for current hardware, and maintain a rehash path when users log in with older credentials. Argon2id is my first choice for new systems, while bcrypt

Never store passwords as raw strings, and don’t invent your own hashing scheme. I use bcrypt with a cost that’s calibrated for the environment (fast enough for login throughput, slow enough to resist offline cracking). The trick is to treat the cost a
