    description: >-
      DIDKit is SpruceID's cross-platform toolkit for working with W3C
      Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). The
      DIDKit HTTP server exposes REST endpoints for issuing, presenting, and
      verifying verifiable credentials and verifiable presentations using
      standard cryptographic proofs. It implements the W3C VC API specification
      and supports multiple DID methods including did:key, did:web, did:ethr,
      and did:tz. Note: DIDKit HTTP does not include built-in authorization and
      should be deployed behind a reverse proxy in production.

  - name: SpruceID Sign-In with Ethereum (SIWE) API
    description: >-
      Sign-In with Ethereum (SIWE) enables Ethereum accounts to authenticate
      with off-chain services by signing a standardized message format (EIP-4361).
      SpruceID's SIWE library provides client and server implementations in
      TypeScript for integrating Ethereum wallet-based authentication into web
      applications. The SIWE-OIDC component wraps SIWE in an OpenID Connect
      Identity Provider, enabling drop-in integration with OAuth 2.0 and OIDC
      flows. Supported wallets include MetaMask, Coinbase Wallet, and any
      WalletConnect-compatible wallet. ENS domain resolution is included for
      human-readable usernames.

  - name: SpruceID SSI Core Library API
    description: >-
      The SpruceID SSI (Self-Sovereign Identity) core library provides a
      comprehensive Rust API for signing, issuing, and verifying W3C Verifiable
      Credentials and JSON Web Tokens. It supports VC Data Model 1.1 and 2.0,
      JWT-VC, Data Integrity proofs, BBS+ selective disclosure, and a wide range
      of cryptographic signature suites including EdDSA, secp256k1, P-256, and
      more. The library has undergone a Trail of Bits security audit and serves
      as the foundation for DIDKit and other SpruceID tooling.

  - name: SpruceID OID4VCI Credential Issuance API
    description: >-
      SpruceID's OID4VCI (OpenID for Verifiable Credential Issuance) Rust
      library implements the OpenID4VC credential issuance protocol, enabling
      credential issuers to deliver W3C Verifiable Credentials to holder
      wallets. The protocol extends OAuth 2.0 with credential endpoint flows
      including pre-authorized code flow and authorization code flow. Supported
      credential formats include JWT-VC, LDP-VC, SD-JWT VC, and ISO/IEC
      18013-5 mobile documents (mDL). Used as the issuance layer in the
      SpruceKit mobile SDK.

      SpruceID's OID4VP (OpenID for Verifiable Presentations) Rust library
      implements the OpenID4VC credential presentation protocol, enabling
      verifier applications to request and receive verifiable credentials from
      holder wallets. The library handles presentation definitions, selective
      disclosure, and cryptographic proof verification. Supported credential
      formats include JWT-VC, LDP-VC, SD-JWT VC, and ISO/IEC 18013-5 mobile
      driver's licenses (mDL) for offline presentation. Integrates with
      SpruceKit mobile SDKs for iOS and Android wallet apps.
