1Why use Bcrypt instead of SHA-256 for passwords?
Bcrypt is specifically designed for password hashing. Unlike SHA-256, which is optimized for speed (making it vulnerable to brute-force attacks), Bcrypt is intentionally slow and includes a 'cost factor' and built-in salting. This makes it exponentially harder for attackers to use rainbow tables or GPU-powered cracking tools against your user data.
2What is the recommended 'rounds' or 'cost factor' today?
As of 2024, a cost factor of 10 or 12 is recommended for most applications. Higher rounds offer more security but increase the time it takes for your server to verify a login. If you set it too high (e.g., 15+), it may lead to performance bottlenecks or DoS vulnerabilities on your authentication server.
3Does this tool store the passwords I hash?
Never. T00LZ is built on a 'Privacy-First' architecture. All hashing and verification happen 100% locally in your browser using the bcrypt.js library. Your plaintext passwords and resulting hashes are never transmitted to our servers.
