What is Bcrypt and why is it secure?

Bcrypt is a password-hashing function based on the Blowfish cipher. It is secure because it incorporates a salt to protect against rainbow table attacks and is intentionally slow (adaptive) to resist brute-force attacks.

What are Bcrypt salt rounds (cost factor)?

The cost factor determines how many iterations of the hashing algorithm are performed. A higher number increases the time required to hash, making it exponentially harder for attackers to crack passwords.

Is Bcrypt better than MD5 or SHA for passwords?

Yes. MD5 and SHA family algorithms are too fast, making them vulnerable to modern GPU-based brute-force attacks. Bcrypt’s built-in slowness and salting make it far superior for storing user passwords.

Bcrypt: Secure Password Hashing

Bcrypt is a robust password-hashing function based on the Blowfish cipher. It is specifically designed to be slow and computationally expensive, making it highly resistant to brute-force and rainbow table attacks.

One of its key features is the use of a salt to protect against precomputed hash attacks. Additionally, Bcrypt is adaptive, meaning the work factor (salt rounds) can be increased over time to keep up with faster hardware.

Why Choose Bcrypt?

Adaptive Security: Adjustable work factor to maintain security as hardware improves.
Salted Hashes: Prevents rainbow table attacks.
Industry Standard: Widely trusted for password storage in secure applications.
