Bcrypt Generator

Generate a bcrypt hash from a password or text value online. Enter your text, choose the number of salt rounds, generate the hash, and copy the result for development or testing.

Strength: Strong

What Is a Bcrypt Generator?

A bcrypt generator is an online tool that converts a password or text value into a bcrypt hash. Bcrypt is a password-hashing algorithm designed to make brute-force attacks more computationally expensive.

Unlike encryption, bcrypt is a one-way hashing algorithm. A bcrypt hash is not designed to be decrypted or converted back into the original password.

How to Generate a Bcrypt Hash?

You can generate a bcrypt hash in a few simple steps:

  1. Enter a password or text value in the Password / Text field.

  2. Set the Salt Rounds value.

  3. Review the indicated hash strength.

  4. Click Generate Hash.

  5. Copy the generated bcrypt hash.

The same password can produce different bcrypt hashes when generated multiple times because bcrypt uses a unique salt.

What Are Bcrypt Salt Rounds?

Salt rounds determine the computational work used when generating a bcrypt hash. Increasing the number of rounds generally makes the hashing process slower and more expensive to perform.

This additional computational cost is an important part of bcrypt's design because it can make large-scale password guessing more difficult.

The appropriate number of salt rounds depends on your application's hardware, security requirements, and acceptable authentication time. Avoid choosing a value solely because it is higher; test the performance within your own application environment.

Can You Decode a Bcrypt Hash?

No. A bcrypt hash is not designed to be decoded or reversed into the original password.

Bcrypt Hash Example

Input: my-password

Output: 2b10$p7v5qxt7ui9bXktcGFzc3dvcmRwN3Y1cXh0N3VpOQ=

The actual output will vary because bcrypt generates a salt during hashing. As a result, hashing the same password more than once does not necessarily produce the same hash.

Frequently Asked Questions

What is a bcrypt generator? add
A bcrypt generator creates a bcrypt hash from a password or text value. Bcrypt is a one-way password-hashing algorithm that uses a salt and configurable computational work to make password guessing more difficult.
What are bcrypt salt rounds? add
Bcrypt salt rounds control the computational work required to generate a hash. Higher values generally require more processing time, so the appropriate setting should be selected based on security requirements and application performance.
Can I convert a bcrypt hash back to a password? add
No. Bcrypt is designed as a one-way hashing algorithm and cannot normally be reversed to recover the original password. Applications verify passwords using the stored bcrypt hash instead.
Why does bcrypt generate different hashes for the same password? add
Bcrypt uses a random salt when creating a hash. This means the same password can produce different bcrypt hashes, which helps prevent attackers from identifying identical passwords through matching hash values.
