Password hashing for user authentication
Store and verify passwords with bcrypt or Argon2id at the edge. Eliminate the latency of round-tripping to a central auth server and the operational burden of rotating CPU/memory cost factors.
Twelve concrete production workloads our APIs were designed for. Each one is implemented in the matching API listed below, and each one bills at well below $0.001 per call.
Store and verify passwords with bcrypt or Argon2id at the edge. Eliminate the latency of round-tripping to a central auth server and the operational burden of rotating CPU/memory cost factors.
Generate or verify SHA-256/512/BLAKE3 HMAC signatures on inbound or outbound webhooks. Required by Stripe-, Slack-, Shopify-style integrations and trivially cheap to outsource.
Block typos and disposable-email signups before they pollute your user table. Sub-5 ms response means you can validate on blur without making forms feel sluggish.
Normalize any international phone-number format to E.164 before handing it to Twilio, Telnyx or AWS SNS. Detect mobile vs. landline and reject obviously-invalid numbers up-front.
Luhn-check card numbers and detect brand in the browser-adjacent edge — without exposing the number to your origin or any third-party processor. Reduce decline rates before the request hits Stripe.
Full ISO 13616 mod-97 checksum (not just a regex). Use it before any SEPA transfer to surface user typos and reject invalid country codes.
Generate QR codes on demand for short-lived URLs, contact cards, Wi-Fi credentials and event check-ins. SVG output scales pixel-perfectly to any print or screen size.
Render EAN-13 or UPC-A barcodes for product labels, catalog pages and packaging. Output is clean SVG you can drop into PDFs or print directly.
Generate Code 128 barcodes for tracking IDs, SKUs and order numbers. Inline-SVG fits into any thermal-printer-friendly PDF or HTML label.
Generate cryptographically-secure UUIDs, hex or base64 tokens for API keys, session IDs, password-reset links and one-time codes. Backed by the platform CSPRNG.
Compute SHA-256 or BLAKE3 digests at the edge to fingerprint uploaded files, dedupe cache entries, verify download integrity and key immutable objects in S3-style storage. BLAKE3 is the fastest cryptographic hash shipped here — useful when you are hashing megabytes per request.
Mint a unique QR code per ticket, badge or guest pass — encode a signed token, a short-lived URL, or a numeric ID. SVG output renders perfectly on a phone screen, in a printed PDF, or on a wristband sticker, and high error-correction levels survive crumpled paper.
