Bcrypt Generator

Hash passwords securely using the Bcrypt algorithm.

Password to Hash
Higher = slower but more secure

Note: Bcrypt generates a different hash each time for the same password (due to random salt). This is a feature, not a bug.

Tips
  • Bcrypt is the recommended algorithm for password hashing.
  • Cost rounds of 10–12 is ideal for most applications.
  • Each hash includes a salt, making rainbow table attacks impossible.

What is Bcrypt Generator?

A bcrypt generator is a tool that applies the bcrypt password hashing function to a plain-text input and produces a secure, salted hash string that cannot be reversed to its original value. Bcrypt is the industry standard algorithm for storing user passwords securely in databases. A bcrypt password generator incorporates a configurable work factor (cost factor) that intentionally slows down the hashing process, making brute-force attacks computationally expensive even with modern hardware. The output of a bcrypt 2b generator begins with the prefix $2b$ followed by the cost factor and the hash string.

How to Use Bcrypt Generator

1
Open a trusted bcrypt generator tool in your browser or use a programmatic library in your application code.
2
Enter the plain-text password or string you want to hash into the input field of the hash password generator bcrypt tool.
3
Select a cost factor (salt rounds). A value of 12 is the current recommended minimum for most production applications.
4
Click Generate. The bcrypt hash generator produces a 60-character hash string beginning with $2b$ if using the bcrypt 2b generator format.
5
Store only the resulting hash string in your database. Never store the original plain-text password alongside or instead of the hash.
6
To verify a password at login, run the entered password through the same bcrypt password generator algorithm and compare the output hash against the stored value using a constant-time comparison function

Why Use Bcrypt Generator?

Adaptive cost factor: The bcrypt hash generator work factor can be increased over time as hardware becomes faster, ensuring the hash remains computationally expensive to brute-force.
Built-in salting: Every output from a bcrypt password generator includes a unique random salt, preventing rainbow table attacks and ensuring identical passwords produce different hash strings.
Irreversibility: Bcrypt produces a one-way hash. There is no mathematical method to recover the original password from a bcrypt 2b generator output, even with full access to the hash string.
Industry standard: Bcrypt is natively supported in PHP, Node.js, Python, Ruby, Java, and every major web framework, making a hash password generator bcrypt the most portable choice.
Resistance to GPU attacks: Unlike MD5 and SHA algorithms, bcrypt is specifically designed to perform poorly on GPU hardware, which significantly limits the viability of large-scale cracking attempts.
Compliance support: Regulatory frameworks including PCI DSS and GDPR require that passwords be stored using strong, irreversible hashing. A bcrypt generator meets these requirements.
