Bcrypt Generator

Generate and verify bcrypt hashes instantly with this free browser-based tool. Works across all major browsers and operating systems - ideal for developers, system administrators, and security researchers.

What is BCRYPT?

Bcrypt is a password hashing algorithm built on the Blowfish cipher. It’s intentionally slow and adaptive, making brute-force attacks more difficult. A key feature of bcrypt is the cost factor (also called rounds), which defines how computationally expensive the hash calculation is. This ensures bcrypt remains secure even as hardware becomes faster, making it one of the most trusted methods for password protection in modern applications.

Example

Input:

keydecryptor

Output:

$2b$10$b6n/5CBejUVXfK8kf7z9I.Rqv34HwgzRlXoImf35bg9C6IMa/YRYm

FAQ

  1. Is this bcrypt generator free?

    Yes. This bcrypt tool runs entirely in your browser - no installation or server required.

  2. What is the cost factor in bcrypt?

    The cost factor (or rounds) defines how many times the algorithm is applied. Higher values increase security but also make hashing slower.

  3. Can I use this to verify a bcrypt hash?

    Yes. Paste a hash and its original password into the verifier to instantly check if they match.

  4. Which bcrypt hash formats are supported?

    This tool supports common bcrypt variants, including $2a$, $2b$, and $2y$.
