Question 1

What is bcrypt?

Accepted Answer

Bcrypt is a password hashing function designed to be computationally expensive, making brute-force attacks impractical. It includes a salt and configurable cost factor.

Question 2

What are bcrypt rounds?

Accepted Answer

Rounds (cost factor) determine how many iterations the algorithm performs. Higher rounds mean slower hashing, which increases security. Common values are 10-12.

Question 3

Is this a real bcrypt implementation?

Accepted Answer

This tool uses multiple SHA-256 iterations to simulate bcrypt cost behavior in the browser. For production use, use a server-side bcrypt library.

Question 4

What cost factor should I use?

Accepted Answer

For most applications, a cost factor of 10-12 provides a good balance between security and performance. Higher values (13+) are more secure but slower.

Question 5

Is my password sent to a server?

Accepted Answer

No. All hashing happens locally in your browser. Your password never leaves your device.

Question 6

Why is bcrypt better than SHA-256 for passwords?

Accepted Answer

Bcrypt is intentionally slow and includes a salt, making it resistant to rainbow table and brute-force attacks. SHA-256 is too fast for password hashing.
