Split-Key Verification

This package uses split-key authentication. To verify, you need to reveal Zone B on the physical label and enter the public key below.

In production, you would scratch off Zone B on the physical label to reveal the 64-character hex key.

⚠️ Test with Sample Data
Load the official DSPIP test vector from the Internet-Draft specification. This uses a publicly known test key and should verify successfully.
