# Bcrypt Hash Engine MCP for AI Agents AI Agent Connect

> Bcrypt Hash Engine allows your AI agent to securely hash and verify user passwords using the industry-standard bcrypt algorithm. It handles salt generation automatically and supports configurable cost factors for different security requirements. Since it's pure JavaScript, it runs anywhere without needing complex native builds.

## Description

When your agent builds a user registration flow, the last thing you want is it storing passwords in plain text. That is a security incident waiting to happen. This Connector gives your agent the ability to handle password security correctly from the start. It uses the same logic that major platforms like GitHub and Dropbox rely on. You don't have to worry about manual salt management or the complexity of native C++ bindings because this is pure JavaScript. It works across different environments like Cloudflare Workers or standard Node.js setups. By adding this to your Vinkius catalog, you ensure that any authentication flow your agent generates follows modern security best practices. It handles the heavy lifting of making sure passwords are computationally expensive to crack while still being fast enough for a snappy user experience. You get a tool that handles the math of security so you can focus on building the actual features of your app.

## Tools

### bcrypt_verify
Compares a plaintext password against a stored hash to see if they match. It returns a simple boolean result.

### bcrypt_hash
Creates a secure hash from a plaintext password using configurable salt rounds. It handles unique salt generation automatically.

## Prompt Examples

**Prompt:** 
```
I'm building a new sign-up page. Can you take the password 'Secret123!' and give me the hash for my database?
```

**Response:** 
```
Here is the secure hash for your database: `$2a$10$N9qo8uLOickgx2ZMRZoMye...` (60 chars). This includes a built-in salt and is ready for your INSERT statement.
```

**Prompt:** 
```
A user just entered their password for login. The hash in my DB is `$2a$10$N9qo8uLOickgx2ZMRZoMye...`. Does it match 'Secret123!'?
```

**Response:** 
```
**Checking credentials...**

- **Match:** Yes (True)
- **Status:** The password is correct. You can proceed with the login.
```

**Prompt:** 
```
My security team says I need to move to 12 salt rounds for our financial app. Hash 'UserPass456' for me with that setting.
```

**Response:** 
```
**Generating a high-security hash with 12 salt rounds...**

- **Hash:** `$2a$12$K3...` 
- **Security Level:** Financial Grade 
- **Note:** This is intentionally slower to protect against brute-force attacks.
```

## Capabilities

### Generate secure password hashes
Your agent creates a one-way string from a plaintext password that is resistant to brute-force attacks.

### Verify user credentials
The agent checks if a login attempt matches the stored hash and returns a simple true or false.

### Set custom salt rounds
You can define the computational cost to meet specific security requirements for different types of data.

### Automate salt generation
The Connector creates a unique random salt for every hash so you don't have to manage them manually.

### Run in serverless environments
The pure JavaScript implementation works in Lambda and Edge functions without needing any compilation.

## Use Cases

### Building a new sign-up form
A developer needs to create a registration page and wants the agent to hash the password field before saving it to a SQL database.

### Fixing a security vulnerability
A security audit finds plaintext passwords and needs a script to re-hash all existing user credentials to a higher salt round.

### Handling user login
A user tries to log in and the agent needs to check if the input matches the hash stored in the database without doing manual string math.

### Meeting financial compliance
A developer is building a banking app and needs to set salt rounds to 14 to meet strict regulatory standards.

## Benefits

- Stop storing plaintext passwords by using bcrypt_hash to generate secure, one-way strings immediately during registration.
- Eliminate manual salt management since bcrypt_hash handles unique salt generation for every single password automatically.
- Adjust security levels easily by changing the salt rounds to meet specific requirements for financial or government data.
- Deploy to serverless environments like Cloudflare Workers or AWS Lambda without any native compilation errors or node-gyp issues.
- Prevent common authentication bugs by using bcrypt_verify instead of trying to compare hashes directly in your code.

## How It Works

The bottom line is your agent gets professional-grade password security without the headache of manual salt management.

1. Connect the Bcrypt Hash Engine to your AI client via the Vinkius dashboard.
2. Tell your agent to hash a password or verify a login attempt.
3. Receive the resulting hash or a simple boolean match result.

## Frequently Asked Questions

**Does Bcrypt Hash Engine handle salt generation for me?**
Yes, it automatically generates a unique random salt for every password you hash. You don't need to manage or store salts separately in your database.

**Can I use Bcrypt Hash Engine in a serverless environment like AWS Lambda?**
Yes, because this Connector uses pure JavaScript, it doesn't require any native compilation. It works perfectly in Lambda, Edge functions, and Cloudflare Workers.

**How do I check if a user's password is correct using Bcrypt Hash Engine?**
You provide the plain password the user typed and the hash you have stored in your database. The Connector will tell you if they match.

**Can I change the security level of the hashing?**
Yes, you can specify the salt rounds. For standard apps, 10 is the default, but you can go up to 16 for high-security needs like government or financial data.

**Is this Connector safe for production use?**
Yes, it uses the same bcrypt algorithm used by major tech companies. It's designed to be intentionally slow to prevent brute-force attacks.

**Do I need to install anything extra to use Bcrypt Hash Engine?**
No, this Connector handles everything. Your AI agent will call the tools directly to perform the hashing or verification.

**Why bcrypt instead of SHA-256 or MD5 for passwords?**
SHA-256 and MD5 are fast — that's the problem. An attacker can try billions of hashes per second. Bcrypt is intentionally slow (configurable via salt rounds), making brute-force attacks economically infeasible.

**What salt rounds should I use for a financial application?**
12 minimum. Each additional round doubles the computation time. 10 = ~100ms, 12 = ~400ms, 14 = ~1.6s. Balance security vs. login latency for your use case.

**Can I verify a password without knowing the salt?**
Yes — that's the beauty of bcrypt. The salt is embedded in the hash string itself ($2a$10$...). Just pass the password and the stored hash to bcrypt_verify.
