Ghost Signature: Cryptographic Receipts for AI Output Using Ed25519 and JWKS
A new API tool called Ghost Signature has been introduced to address the growing challenge of verifying AI-generated content. Rather than relying on inaccurate AI detection methods that attempt to reverse-engineer authorship from text, this solution allows AI agents to cryptographically sign their outputs at the moment of generation using the Ed25519 algorithm. The system provides three main endpoints: one for signing content with a private key, a public endpoint for anyone to verify signatures without authentication, and a JWKS endpoint for managing public key rotation. By attaching metadata such as the agent ID, key ID, signature, and timestamp to AI outputs, recipients can independently confirm that the content originated from a specific agent and remains unmodified. This approach mirrors established cryptographic verification standards used in email (DKIM) and software updates. The service is available via RapidAPI, offering a free tier for limited usage, and aims to create a trustless environment where provenance is proven rather than detected, enhancing transparency and accountability in AI communications.
