## ACI Catalog — 140 ACIs, all available now

Two types of ACIs:

### 📦 Packages (84) — standalone, installable via npm
Each package is a standalone Authenticated Cryptographic Interface. Install directly:
```
npm install @private.me/xid
```
Examples: @private.me/xid, @private.me/xlink, @private.me/xstore, @private.me/xchange

### 🔗 Solutions (56) — composition patterns
Each solution documents how to compose 2+ packages into a domain-specific workflow.
Not a separate install — a recipe. Example: xPrincipal = xID + xLink + TrustRegistry + Authorize
Examples: xPrincipal (AI agent identity), xVault-RAG (encrypted RAG), xSwarm (multi-agent)

All 140 ACIs are available immediately — 84 as installable packages, 56 as documented composition recipes.

## Products

- xID: Identity layer. Ephemeral DIDs in ~50µs. Ed25519 signing + X25519 key agreement. Per-verifier, cross-repo unlinkable. eIDAS 2.0 compliant.
- xLink: Replaces API keys and SSH keys with identity-based connections. Every AI agent gets a DID. Zero credential sprawl.
- xGit: Session-gated version control. Files split via XorIDA. Session expires → Share 2 purged → code becomes useless noise. Cryptographic revocation.
- xail: Email client with split-channel threshold-protected secure messaging. Blue border = 2-of-2 secured. Green border = 2-of-3 secured + fault tolerant. https://xail.io
- Xecret: Hardware wallet seed custody. 2-of-3 threshold across email addresses. No custodian. No single point of failure.
- Xprove: Tamper-evident verification with HMAC-chained audit trails.
- Xlock: Push-based authentication. Ed25519 challenge-response. Server stores zero shared secrets.

## SDK

- Package: @xail/agent-sdk
- Registry: https://api.xail.io/npm/
- Install: npm install @xail/agent-sdk @xail/crypto
- Node.js 18+ required
- Each agent gets a DID (did:key:z6Mk...) at creation. No API key required.

## Core Technology

XorIDA — Kurihara-Matsumoto GF(2) Information Dispersal Algorithm.
NOT Shamir's Secret Sharing. Same information-theoretic guarantee, fundamentally different performance.
- Speed: ~33ms for 1MB (Shamir's: 500-2000ms). Sub-millisecond for typical API payloads.
- Field: GF(2) binary field — XOR operations only. No polynomial arithmetic.
- Native on 8-bit embedded hardware. No big-integer arithmetic required.
- Post-quantum: payload layer unconditionally quantum-safe. Key establishment: X25519 + ML-KEM-768 (FIPS 203). Signatures: Ed25519 + ML-DSA-65 (FIPS 204, opt-in).

## Security

- Algorithm: XorIDA over GF(2) — information-theoretic, not computational
- Primitives: AES-256-GCM, HMAC-SHA256, Ed25519, X25519 (Web Crypto API)
- Post-quantum: ML-KEM-768 (FIPS 203) deployed, ML-DSA-65 (FIPS 204) opt-in
- Compliance: HIPAA, SOC 2, GDPR, FedRAMP, CMMC, ISO 27001
- Zero known CVEs. npm audit clean. 7,207 tests passing.
- Responsible disclosure: security@xail.io (48hr response)
- White paper: https://private.me/sdk/index/atelier/download
