- **Category:** Cryptography

- **Keywords:** bcrypt, hash, password, security, generator, cryptography

## Overview

The Bcrypt Generator is a secure utility designed to create robust password hashes using the industry-standard bcrypt algorithm, ensuring your sensitive credentials are protected with an adjustable cost factor.

## Inputs

- **Password** (text): Enter password to hash...
- **Cost Rounds** (number): Enter cost factor (4-12)

## When to use

- When you need to generate a secure hash for a user password before storing it in a database.
- When testing authentication workflows that require bcrypt-compatible password verification.
- When you need to increase the computational cost of hashing to defend against brute-force attacks.

## How it works

- Enter the plain-text password you wish to secure into the input field.
- Select a cost factor (rounds) between 4 and 12 to determine the hashing complexity.
- Click the generate button to produce a unique, salted bcrypt hash string.

## Use cases

- Securing user authentication systems in web applications.
- Generating test data for database migration and security audits.
- Verifying password hashing implementation logic during development.

## Frequently asked questions

### What is the purpose of the cost rounds?

The cost factor determines how many iterations the algorithm performs; higher values make the hash more resistant to brute-force attacks but require more processing time.

### Is this tool secure for production passwords?

While this tool generates valid hashes, you should always perform password hashing on your own secure server-side infrastructure to prevent sensitive data exposure.

### Can I reverse a bcrypt hash to get the original password?

No, bcrypt is a one-way cryptographic hash function designed to be irreversible.

### What is the recommended range for cost rounds?

A range of 10 to 12 is generally recommended to balance security and performance for modern web applications.

### Does the tool store my passwords?

No, this utility processes your input locally and does not store or transmit your passwords or generated hashes.

Three modes: (1) generate a fresh verifier + challenge from cryptographically secure random bytes at 256/384/512/768-bit entropy, (2) audit a verifier you already have against the RFC — length (43–128), charset \[A-Za-z0-9-._~\] and ≥256-bit entropy, and (3) verify a verifier/challenge pair by recomputing BASE64URL(SHA256(verifier)). Optionally build the full authorization-request URL and token-exchange body. Complements the generic nonce-generator (which only emits a verifier+challenge pair) with RFC-compliance auditing and pair verification.
