Bcrypt is a password hashing function designed to be computationally expensive, making brute-force attacks slower. It includes a salt to protect against rainbow table attacks.

Bcrypt Hash Generator — Create Secure Password Hashes

Q: Is bcrypt better than SHA-256 for passwords?

Yes, bcrypt is specifically designed for password hashing. It is deliberately slow and includes a salt, making it much more resistant to brute-force and rainbow table attacks than general-purpose hash functions like SHA-256.

Intro

A bcrypt generator creates a secure bcrypt hash from a plain-text password. Bcrypt is widely used for password storage because it is intentionally slow and includes a built-in salt. That makes brute-force attacks harder than with fast hash functions like MD5 or SHA-1. If you are building a login system, testing authentication logic, or preparing seeded users for a database, a bcrypt generator helps you produce hashes that are ready to store.

The most important part of bcrypt is the cost factor. A higher cost increases the time needed to compute the hash, which improves resistance to password cracking. Modern applications often choose a cost that feels fast enough for users but expensive enough for attackers. The hash output also contains the algorithm version, cost, salt, and final hash value, so you usually only need to store a single string.

This tool is useful for developers, QA engineers, and admins who need to verify password hashing behavior without writing code each time.

How to Use

1. Enter the password or sample text you want to hash. 2. Choose the bcrypt cost factor if the tool provides that option. 3. Click Generate to create the bcrypt hash. 4. Copy the output and store it in your database, config, or test fixture.

Examples

Input: MySecurePass123!

Output: $2b$12$...bcrypt-hash...

Input: admin with cost 10

Output: $2b$10$...bcrypt-hash...

Same password hashed twice

Input: secret123 Output 1: $2b$12$...A... Output 2: $2b$12$...B... Result: the hashes differ because bcrypt uses a unique salt.

Tips

Use bcrypt for password storage, not for general file hashing or checksums.
Prefer a cost factor that matches your server capacity and security needs.
Never store plain-text passwords alongside the bcrypt hash.

FAQ

Why are two bcrypt hashes different for the same password?

Because bcrypt generates a new random salt for each hash.

Can I reverse a bcrypt hash?

No. Bcrypt is designed as a one-way password hashing algorithm.

Is bcrypt better than SHA-256 for passwords?

For password storage, yes. Bcrypt is intentionally slow and salted, which makes it far more suitable than fast general-purpose hashes.
