Quick Start

View Full Guide
1

Generate Keys

Create a secp256k1 key pair for SHIP signing. Same keys work with Ethereum/Bitcoin.

2

Publish to DNS

Add your public key with types=SHIP at selector._dspip.yourdomain.com

3

Sign & Generate

Create SHIP payloads with issuer/subject, choose privacy mode, sign with ECDSA, and generate QR codes.

4

Verify

Scan 6-field QR codes, fetch public keys from DNS, and verify SHIP signatures.

What is DSPIP?

The Digital Signing of Physical Items Protocol enables cryptographic authentication of shipping using SHIP type QR codes, DNS-based key distribution, and ECDSA signatures.

  • ✓ SHIP type - shipping-focused signature format
  • ✓ Privacy modes - standard, encrypted, or split-key
  • ✓ Decentralized - DNS-based key distribution
  • ✓ Issuer/Subject model - clear sender and recipient roles
  • ✓ Last Mile Provider support - privacy-preserving delivery
  • ✓ Open standard - no proprietary technology
