What is Bcrypt Generator?

Bcrypt is a password-hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It automatically includes a random salt in the output hash.

This tool lets you hash passwords using bcrypt with an adjustable cost factor (4-12). A higher cost factor means more rounds of hashing, which increases security but takes longer. The default of 10 is a good balance.

FAQ

What is bcrypt?
Bcrypt is an adaptive password hashing function based on the Blowfish cipher. It includes a salt to protect against rainbow table attacks and is intentionally slow to resist brute-force attempts.
What cost factor should I use?
A cost factor of 10 is the common default. Use 12 for higher security at the cost of slower hashing. Values below 8 are not recommended for production.
Is the password sent to a server?
No. The bcrypt hash is generated entirely in your browser using JavaScript. Nothing is transmitted.
