SHA256 Hash API

Compute cryptographic SHA256 hashes programmatically via a simple REST API. Send any string or binary data and receive the 64-character hex digest — the same output as openssl dgst -sha256 or Python's hashlib.sha256.

How it works

POST your input data as a JSON string. The API computes a SHA-256 digest using Node.js's built-in crypto module (no external dependencies) and returns the lowercase hex-encoded 32-byte hash. Processing is deterministic: the same input always produces the same output.

Use cases

• Verify file integrity — hash a downloaded file and compare to a published checksum
• Generate cache keys — create a stable identifier for any piece of content
• Build content-addressable storage systems or deduplication pipelines
• Implement API request signing where SHA256 is the required digest algorithm
• Generate unique identifiers from composite fields without a database sequence

Examples

Three real-world scenarios showing how developers use SHA256 Hash in production.

curl -X POST https://slopshop.gg/v1/crypto-hash-sha256 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "mysecretpassword"}'

curl -X POST https://slopshop.gg/v1/crypto-hash-sha256 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "user:42:profile:settings"}'

curl -X POST https://slopshop.gg/v1/crypto-hash-sha256 \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"data": "contents of important document..."}'

Code examples

curl

curl -X POST https://slopshop.gg/v1/crypto-hash-sha256 \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "your data here"}'

Python

import requests

response = requests.post(
    "https://slopshop.gg/v1/crypto-hash-sha256",
    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-sha256", {
  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-sha256
slop crypto-hash-sha256 '{"input": "your data here"}'
