About Bcrypt Generator
Hash passwords using the bcrypt algorithm, the industry standard for secure password storage. Choose the number of salt rounds to balance security and performance. Also verify if a plaintext string matches an existing bcrypt hash.
How to use
- Enter a password or string in the input field.
- Select the number of salt rounds (10 is the default, 12+ for high security).
- Click Generate Hash to create the bcrypt hash, or paste a hash and click Verify to check a match.

Frequently Asked Questions
FAQs about Bcrypt Generator
What is bcrypt?
Bcrypt is a password hashing function designed to be slow and computationally expensive, making brute-force attacks impractical. It is the recommended algorithm for storing passwords.
How many salt rounds should I use?
10 rounds is the default and suitable for most applications. Use 12 for higher security. Each additional round doubles the computation time.
Can I reverse a bcrypt hash?
No. Bcrypt is a one-way function — you cannot recover the original password from the hash. You can only verify if a given password matches a hash.
What is the Verify button for?
Verify checks if the plaintext string you entered matches the hash in the output field. This is useful for testing existing hashes.
Is my data safe?
Yes. All hashing is performed in your browser using bcryptjs. No passwords or hashes are sent to any server.
