TauthC2PA Media Provenance Platform

Sign, verify, and anchor your media to a permanent chain of trust. Backed by Azure Key Vault and Ethereum.

🔏

C2PA Signing

Embed verifiable provenance data into JPEG, PNG, PDF, and video files using the open C2PA standard.

🔑

All signing keys live in Azure Key Vault (ES384). Private key material never touches your application server.

⛓️

Every signed asset is anchored on Ethereum Sepolia. File hashes are immutable and publicly auditable on-chain.

🏢

Invite your team, assign roles (admin · signer · viewer), and manage API keys within your organisation namespace.

📜

Industry-standard certificate revocation via CRL (served by nginx) and an OCSP responder signed with your CA keys.

🛠️

Drop-in SDKs for Python and JavaScript/TypeScript with full type coverage and async-first design.
