# Hash Checksum Calculator MCP

> Hash Checksum Calculator MCP allows you to verify the integrity of files and data streams through various cryptographic and non-cryptographic algorithms. You can generate MD5, SHA-1, SHA-256, SHA-512, and CRC32 checksums directly within your AI client, checking for any bitrot or bitflips in your datasets. It's the easiest way to ensure that what you downloaded or transferred is exactly what it was intended to be.

## Description

If you are working with sensitive data transfers, software distributions, or large datasets, even a single flipped bit can ruin everything. This MCP lets your agent perform critical security and integrity checks without you ever leaving your chat interface. Instead of hunting for online converters or running command-line utilities, you just hand the content to your AI client and ask it to check the hash. It works with standard algorithms like SHA-256 for high-security needs or CRC32 when you just need a quick integrity check on non-critical files. Whether you are verifying software signatures or checking if a file transfer was successful, everything is integrated into your workflow through Vinkius. You can quickly compare two strings to see if they match or validate that a hash string follows the correct format for its specific algorithm.

## Prompt Examples

**Prompt:** 
```
Generate an MD5 hash for 'hello world'.
```

**Response:** 
```
The MD5 hash is 5eb63bbbe01eeed093cb22bb8f5acdc3.
```

**Prompt:** 
```
Compare these two SHA-256 hashes: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 and 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824.
```

**Response:** 
```
The hashes are identical.
```

**Prompt:** 
```
Is this string a valid SHA-256 hash: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824?
```

**Response:** 
```
Yes, the string is a valid SHA-256 hash.
```

## Capabilities

### Verify data integrity
Run checksums on any text or file content to ensure no corruption occurred during transfer.

### Generate cryptographic hashes
Create MD5, SHA-1, SHA-256, and SHA-512 signatures for files and datasets.

###  checksum comparison
Check if two different hash strings are identical to catch mismities immediately.

### Validate hash structures
Confirm that a provided hash string matches the expected length and character set of its algorithm.

## How It Works

The bottom line is you get instant, automated integrity checks directly inside your conversation.

1. Connect your preferred AI client to this MCP via Vinkius.
2. Paste the data or file content you need to verify into your agent's prompt.
3. Ask your agent to generate a checksum, compare hashes, or validate a format.

## Frequently Asked Questions

**What algorithms are supported?**
Supported algorithms include MD5, SHA-1, SHA-256, SHA-512, and CRC32. Tools available: `your_tool_name`.

**How do I use HMAC?**
When using `compute_hash`, provide a `secretKey` to trigger the HMAC construction.

**Is the comparison secure?**
Yes, `compare_hashes` uses a constant-time algorithm to prevent timing attacks.
