BACKEND WORK SAMPLE · 01

The request is right.
Are the signed bytes?

A small RSA workbench for finding the difference between the request you sign and the request you send.

Ready to run local signing checksRSA-2048 / SHA-256 / PKCS#1 v1.5

01 Request bytes

Run the checks to inspect the payload.

A temporary key is created in this browser. Requests and keys stay here; this sample makes no API calls.

  1. Run the checks to see which changes invalidate the signature.
WHY IT MATTERS

Serialize once. Sign those bytes. Send those same bytes.

Equivalent JSON can still produce a different signature.

FROM SAMPLE TO STORE

Authentication first.
Order recovery next.

The first store milestone is a verified signature test and confirmed outbound IP. Paid-order handling then uses WooCommerce’s order lifecycle and Action Scheduler, with ambiguous responses reconciled before another recharge attempt.

This sample demonstrates local cryptographic verification. The store’s supplied API documentation defines its integration and acceptance tests.
