IC Auth

Independent application authentication protocol libraries for the Internet Computer, with a wallet-authentication service planned.

The accepted scope includes IC signatures, application tokens, local application sessions and wallet-backed IC identities. Canic will consume the libraries; applications such as Toko will integrate through a documented client/service contract. The libraries and reference service must not depend on either project.

Status

The Rust workspace implements passive token/proof contracts, validated protocol identifiers, canonical signed encoding, optional IC signature/application-token verification and atomic session/replay admission extracted from Canic. Both libraries are published on crates.io at 0.1.14; see the signature, token and session contracts. Durable canister adoption remains pending. Bounded signature preparation and retrieval includes explicit host certification composition. Released IC Testkit qualification checks real certification, upgrades and signed ingress; this internal fixture does not implement a wallet login provider. The private browser client now implements injected authenticated-identity/token lifecycle machinery with generated Candid contracts and an opt-in transactional IndexedDB store. It is not published; issuer adapter qualification and consumer adoption remain pending. Wallet login remains unimplemented. Tokens and local sessions do not grant application resource ownership. The native utility in apps/tooling/ is unpublished and reuses ic-host-fs for release and publication file operations.

Canic still runs its existing implementation. The Canic adoption contract maps the published libraries to its feature, authority, storage and certification boundaries; implementation and acceptance belong in Canic #491.

The types package is ic-auth-protocol-types (Rust import ic_auth_protocol_types). The unrelated ic_auth_types package belongs to another IC-Auth project and does not implement our application token/proof contracts. Crates.io treats hyphens and underscores as colliding names, so changing only the punctuation cannot resolve that conflict.

The future wallet service belongs in apps/wallet-auth/. No accepting wallet endpoint is created before its complete proof verification and service contracts.

With the declared tools prepared, run the focused checks:

make test-types
make test-protocol
make test-signatures
make test-signature-store
make test-tokens
make test-sessions
make test-qualification
make check-wasm

Planned wallet authentication targets Solana message signing without SIWS or ic-siws. NFTs remain in their application's ledger. This service does not mint, index, bridge or custody Solana assets.

Canic integration uses local library calls. It must not add a remote authentication request to every protected application call.
