How to Use the Bcrypt Generator
The Bcrypt Generator helps you create secure password hashes for applications, login systems,
and developer testing. Bcrypt is widely used for password storage because it is intentionally slow and includes
a built-in salt, which makes brute-force attacks harder than with basic hashing algorithms.
To use this tool, enter a password, choose the salt rounds or cost factor, and click
Generate Hash. The tool will instantly create a bcrypt hash in your browser. You can then copy
the hash and use it in development or testing workflows.
You can also paste an existing bcrypt hash into the verification area and test whether a password matches it.
This makes the tool useful not only for generating hashes, but also for checking password-hash matches during development.
Why bcrypt?
Made for passwords: Bcrypt is designed specifically for password hashing.
Built-in salting: It automatically includes a salt in every hash.
Configurable cost: Higher rounds slow hashing to resist attacks.
Widely used: Bcrypt is supported across many web frameworks and backend systems.
Better than fast hashes: It is much safer for passwords than plain SHA1 or MD5.
What are Salt Rounds?
Salt rounds, also called the cost factor, control how much work bcrypt does before generating
the final hash. A higher value increases security, but it also takes longer to compute. For many applications,
values around 10 to 12 are common starting points depending on server performance and security needs.
Important Security Note
This tool is useful for learning, development, and quick testing. For production systems, password hashing should
usually happen on the backend, and passwords should never be exposed in frontend code, logs, or screenshots.
Frequently Asked Questions (FAQ)
Bcrypt is a password hashing algorithm created for secure password storage. It is designed to
be slower than regular hashing algorithms, which helps reduce the effectiveness of brute-force attacks.
Salt rounds are the cost factor used by bcrypt. Higher values increase the work needed to
generate the hash, which improves security but also takes more time.
Yes. Bcrypt is much better for password hashing because it is intentionally slow and includes
salting. SHA1 is not recommended for storing passwords securely.
Yes. Paste the bcrypt hash into the verification field, enter the password, and use the
Verify Password button to test whether they match.
Yes. This bcrypt generator is completely free to use and works directly in your browser without sign-up.
