This cryptographic security tool generates salted bcrypt password hashes directly in your web browser. System administrators seeding database user tables, DevOps engineers provisioning initial admin credentials, and developers configuring htpasswd files can create production-grade bcrypt strings without transmitting unencrypted passwords to third-party cloud generators.

### Hashing Engine and Work Factor Configuration The tool computes hashes using the client-side `bcryptjs` library:

- **Dynamic In-Browser Engine:** Dynamically imports `bcryptjs` directly into your browser tab without making backend API network requests. - **Salt Generation:** Uses `bcrypt.genSalt(rounds)` with a cryptographically secure pseudo-random number generator (CSPRNG) to generate a unique 16-byte salt for every hash invocation. - **Work Factor Rounds:** Configurable cost factor (defaults to 10 rounds, corresponding to $2^{10} = 1,024$ key expansion iterations). Setting higher rounds (such as 12) increases brute-force resistance at the cost of compute duration. - **Standard Modular Output:** Produces standard `$2a$` prefixed 60-character bcrypt hash strings compatible with Node.js bcrypt, Python passlib, PHP password_hash, and Ruby bcrypt.

### Concrete Generation Example Suppose a DevOps engineer generates an initial database password hash:

- **Plaintext Password:** `AdminSecretKey2026#` - **Cost Factor:** 10 rounds

**Execution Steps:** 1. The browser generates a unique random salt (e.g. `$2a$10$e7...qW`). 2. The Blowfish cipher expands the key across 1,024 iterations. 3. The tool returns a 60-character string (e.g. `$2a$10$e7xZb...9mK1LqW`). 4. Copying the result into your database user record safely stores the credential.

### Privacy and Client-Side Execution All salt generation and Blowfish cipher rounds execute 100% locally on your device CPU via client-side JavaScript. Your plain passwords and generated hash values never leave your web browser.
