MD5 Hash API

Generate MD5 checksums via REST API. While MD5 is not cryptographically secure for password hashing, it remains the standard for non-security checksums: file integrity checks, etag generation, and cache key generation where speed matters more than collision resistance.

How it works

POST any string and receive its 32-character MD5 hex digest. Fast and deterministic. For password hashing, use the crypto-password-hash API which uses PBKDF2 with a random salt.

Use cases

• Generate ETag headers for HTTP cache validation
• Compute legacy checksums to match third-party systems that require MD5
• Build deduplication keys for large datasets where speed matters
• Verify file downloads from older systems that publish MD5 checksums

Examples

Three real-world scenarios showing how developers use MD5 Hash in production.

curl -X POST https://slopshop.gg/v1/crypto-hash-md5 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "Hello World"}'

curl -X POST https://slopshop.gg/v1/crypto-hash-md5 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "order_id=12345&amount=99.99¤cy=USD"}'

curl -X POST https://slopshop.gg/v1/crypto-hash-md5 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "john.doe@example.com|2024-01-15|purchase"}'

Python

import requests

response = requests.post(
    "https://slopshop.gg/v1/crypto-hash-md5",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"input": "your data here"}
)
result = response.json()
print(result["data"])

Node.js

const response = await fetch("https://slopshop.gg/v1/crypto-hash-md5", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ input: "your data here" })
});
const { data } = await response.json();
console.log(data);

CLI

# Install the Slopshop CLI
npm install -g slopshop

# Set your API key
export SLOPSHOP_KEY=your_api_key

# Call crypto-hash-md5
slop crypto-hash-md5 '{"input": "your data here"}'
