The Crypto Service ecosystem

Crypto Service provides a complete cryptography stack across 14 specialized packages:

| Package | Role | Description | | :---------------------------------------------------------------------------------------------------------------------------------------- | :------------------ | :----------------------------------------------------------------------------------------------------------------------------- | | @sebastienrousseau/crypto-api | API Schemas | Shared TypeScript types and utilities for the Crypto Service Suite, defining the canonical API surface. | | @sebastienrousseau/crypto-benchmarks | Benchmarks | Benchmarks comparing classical and post-quantum cryptography: ops/sec, latency and throughput. | | @sebastienrousseau/crypto-cbom | CBOM | Cryptographic Bill of Materials generator and auditor (CycloneDX 1.6, SPDX 3.0). | | @sebastienrousseau/crypto-cli | Terminal CLI | Command-line interface: hashing, key generation, encryption, signing, HPKE, Argon2id and CBOM scans, with an interactive menu. | | @sebastienrousseau/crypto-edge | Edge Runtime | Edge-runtime cryptographic operations using the Web Crypto API, optimized for Cloudflare Workers, Vercel Edge, and Deno. | | @sebastienrousseau/crypto-kms | Cloud KMS | Unified KMS interface: AWS KMS and local providers implemented; GCP, Azure and Vault are stubs. | | @sebastienrousseau/crypto-lib | Core Library | Core library: post-quantum ML-KEM, ML-DSA and SLH-DSA, plus classical, modern and OpenPGP cryptography for TypeScript. | | @sebastienrousseau/crypto-lsp | IDE Analysis | Language server that flags weak and quantum-vulnerable cryptography in the editor, with quick fixes. | | @sebastienrousseau/crypto-mcp | AI Agents | Model Context Protocol server exposing cryptography tools to AI assistants and agents. | | @sebastienrousseau/crypto-middleware | Middleware | Cryptographic middleware for Express and Fastify: decrypt requests, encrypt responses, verify HMAC signatures and JWTs. | | @sebastienrousseau/crypto-prisma | ORM Adapter | Transparent field-level encryption extension for Prisma Client, using XChaCha20-Poly1305. | | @sebastienrousseau/crypto-react | React Hooks | React hooks and context provider for client-side cryptographic operations with zero boilerplate. | | @sebastienrousseau/crypto-sdk | Client SDK | A zero-dependency, typed HTTP client for the Crypto Service REST API, with full post-quantum support. | | @sebastienrousseau/crypto-server | HTTP API | A hardened Fastify REST API for cryptographic operations, with rate limiting, OpenAPI schemas, and post-quantum endpoints. | | @sebastienrousseau/crypto-testing | Test Support | Deterministic keys, fast mocks, and test fixtures for crypto-lib | | @sebastienrousseau/crypto-typeorm | ORM Adapter | TypeORM column-level encryption with a single decorator, powered by crypto-lib. | | @sebastienrousseau/crypto-vue (this package) | Vue Composables | Vue 3 composables for client-side cryptography | | @sebastienrousseau/crypto-wasm | Acceleration | Placeholder for a WebAssembly accelerator; no WebAssembly module ships yet. |

Overview

crypto-vue provides Vue 3 composables for client-side cryptographic operations. It wraps @sebastienrousseau/crypto-lib in a reactive API with composables for key generation, symmetric encryption, hashing, and digital signatures. An optional CryptoPlugin supplies global configuration (default key, server URL, API key) via Vue's provide/inject system.

CryptoPlugin

An optional Vue plugin that provides global configuration to all composables via inject/provide.

// main.ts
import { createApp } from "vue";
import { CryptoPlugin } from "@sebastienrousseau/crypto-vue";
import App from "./App.vue";

const app = createApp(App);

app.use(CryptoPlugin, {
  defaultKey: "your-256-bit-hex-key",
  serverUrl: "https://api.example.com",
  apiKey: "your-api-key",
});

app.mount("#app");

| Option | Type | Description | | :----------- | :------- | :------------------------------------------ | | defaultKey | string | Default encryption key (256-bit hex string) | | serverUrl | string | Base URL for the Crypto Service REST API | | apiKey | string | API key for authenticated server requests |

All examples are self-contained TypeScript files in the examples/ directory. Run any example with:

npx ts-node examples/<name>.ts

| Category | Example | Purpose | | :------------- | :-------------------------------- | :-------------------------------------------- | | Plugin | plugin.ts | CryptoPlugin setup and injection | | Key Generation | keygen.ts | Generate Ed25519 and ML-DSA-65 key pairs | | Encryption | encrypt.ts | Secretbox encrypt and decrypt round-trip | | Hashing | hash.ts | SHA-256, SHA3-256, and BLAKE3 hashing | | Signing | sign.ts | Ed25519 sign and verify with tamper detection |

Development

pnpm --filter @sebastienrousseau/crypto-vue run build
pnpm --filter @sebastienrousseau/crypto-vue run test
pnpm --filter @sebastienrousseau/crypto-vue run lint
pnpm --filter @sebastienrousseau/crypto-vue run format

All 18 packages in the Crypto Service workspace maintain a 100% coverage floor across statements, branches, functions, and lines.

Security

Report vulnerabilities privately via GitHub Security Advisories or according to SECURITY.md. Never report security issues publicly.

Cryptographic operations use the @noble/* libraries, Node.js crypto and OpenPGP.js. @noble/post-quantum has not been independently audited and does not guarantee constant-time execution, and no module in this suite is FIPS 140-3 validated. Key zeroization is limited: JavaScript strings and garbage-collected buffers cannot be reliably wiped. See SECURITY.md.

Stability guarantees

Versions advance strictly one step at a time on the 0.0.x line (v0.0.1 → v0.0.2 → v0.0.3 ... → v0.0.999 → v0.1.0). Work for every release iteration begins on a dedicated feat/v<version> branch.

All 18 packages in the workspace move in lockstep. Public API signatures, cipher output formats, and serialization schemas are strictly versioned. Breaking changes to serialized formats or algorithm defaults are considered major breaking changes. Minimum toolchain upgrades (e.g. Node.js LTS floor) are governed by POLICIES.md.
