Generate secure Bcrypt hashes for passwords
Generate and verify bcrypt password hashes with our free online Bcrypt Generator. Bcrypt is the industry-standard password hashing algorithm used by modern web applications to securely store passwords. It incorporates a salt and configurable work factor (cost) to protect against brute-force and rainbow table attacks. Essential for developers building authentication systems.
Enter the password you want to hash in the input field.
Select the cost factor (rounds) - higher means more secure but slower.
Click 'Generate Hash' to create the bcrypt hash.
To verify, enter a password and a hash to check if they match.
A cost factor of 10-12 is recommended for most applications in 2026. Higher values increase security but also increase hashing time. Choose based on your server capacity and security requirements.
Bcrypt is specifically designed for password hashing with built-in salting and adjustable work factor. MD5 and SHA are general-purpose hash functions that are too fast, making them vulnerable to brute-force attacks. Bcrypt intentionally slows down hashing to resist attacks.
Yes! Bcrypt automatically generates a unique random salt for each hash, so hashing the same password twice produces different hash strings. Both will still verify correctly against the original password.
