Bcrypt Tool is a free online utility for generating and verifying bcrypt password hashes. Bcrypt is a password hashing function designed to be slow and resistant to brute-force attacks. Adjust the cost factor (4-15), hash passwords, and verify hashes — all processing happens locally in your browser for maximum security.
Higher rounds = more secure but slower. 10 is recommended for most use cases.
Generate a hash to see the result
Paste an existing bcrypt hash to verify a password against it.
Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It incorporates a salt to protect against rainbow table attacks.

Enter a password
Type or paste the password you want to hash into the input field.
Set the cost factor
Choose a cost factor between 4 and 15 (default 10). Higher values are more secure but slower.
Generate the hash
Click generate to create the bcrypt hash. The hash appears in the output area.
Verify (optional)
Use the verify section below the hash to check if a password matches the generated hash.
