Frequently Asked Questions

SHA-256 is designed to be fast (millions of operations/sec). Bcrypt is intentionally slow and includes a cost factor you can increase as hardware gets faster. It also includes a built-in salt preventing rainbow table attacks.

Cost 10–12 is recommended for most web apps (100ms–400ms per hash). Higher factors increase security but slow down login. The OWASP recommendation is cost 10 minimum. Never go below 8 for production use.

Bcrypt generates a random 128-bit salt each time, which is embedded in the hash output. The verify function extracts this salt automatically — that's why you compare using verify(), not direct string comparison.
