Bcrypt: The Industry Standard for Password Security

Updated Jan 12, 20264 min read

When it comes to storing passwords, never use standard hash functions. Instead, use Bcrypt. Developed in 1999, it remains the gold standard for password security in 2026 due to its unique "Adaptive Hashing" capability.

The 'Slow by Design' Secret

Most hashes (like MD5 or SHA-256) are designed to be fast. But for passwords, speed is a vulnerability. An attacker with a GPU can try billions of SHA-256 hashes per second. **Bcrypt is designed to be slow.** By introducing a 'Cost Factor' (rounds), you can control exactly how long it takes to hash a password, making brute-force attacks economically impossible.

Why Every Dev Needs Bcrypt:

  • Adaptive Security: As computers get faster, you can simply increase the 'Cost Factor' to keep your hashes secure.
  • Automatic Salting: Bcrypt handles salt generation automatically and bakes it into the output string, eliminating common developer errors.
  • Unrivaled Pedigree: It has withstood over 25 years of cryptographic scrutiny without being broken.

🛡️ Secure Practice

For modern web apps, a Cost Factor of **10 to 12** is the 'sweet spot'—fast enough for a user to log in (under 200ms), but slow enough to stop hackers in their tracks.

Generate and Test with Devtobox

Our Bcrypt tool lets you experiment with different cost factors and generates secure, salt-inclusive hashes instantly. It's the perfect companion for anyone building a secure authentication system.
