About this tool

Generate cryptographic hashes for any text string using industry-standard algorithms. Perfect for content fingerprinting, integrity verification, password hashing workflows, and generating unique identifiers. Runs entirely on Node.js native crypto module — no external API, instant response.

Quick Start

curl -X POST https://api.iteratools.com/hash \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "hello world", "algorithm": "sha256"}'

Response

{
  "hash": "b94d27b9934d3e08a52e52d7da7dabfac484efe04294e576b94b5d54acfe",
  "algorithm": "sha256",
  "input_length": 11,
  "hex": "b94d27b9934d3e08a52e52d7da7dabfac484efe04294e576b94b5d54acfe",
  "base64": "uU0nuRpPqzSe5S1nus/axCSOT+BClOV2uUtVVDyv/g=="
}

Supported Algorithms

sha256 — SHA-256 (default, recommended)
sha512 — SHA-512 (maximum security)
sha384 — SHA-384
sha1 — SHA-1 (legacy compatibility)
md5 — MD5 (non-cryptographic, fast checksums)

Request Body

{
  "text": "string (required) — text to hash",
  "algorithm": "string (optional) — md5 | sha1 | sha256 | sha384 | sha512 (default: sha256)"
}

Pricing

$0.001 per request via x402 micropayment on Base (USDC). Zero external API cost — runs entirely on server using Node.js native crypto.
