What problem does it solve?

This Skill enables enterprise-grade zero-knowledge client-side encryption for SvelteKit applications, ensuring plaintext data never leaves the client and servers cannot decrypt user information.

Core Features & Use Cases

  • Zero-knowledge security: All cryptographic operations occur on the client, eliminating plaintext exposure on the server.
  • Key management: KEK/DEK hierarchy with PBKDF2 derivation, AES-256-GCM encryption, and RSA-OAEP authentication.
  • SvelteKit integration: Web Crypto-based primitives with browser-friendly patterns and on-demand resources; fits into Cloudflare Workers, D1, KV, and R2 workflows.
  • Use Case: Enterprises needing privacy-compliant client-side encryption for sensitive user data in modern web apps.

Quick Start

Use the client-side-encryption skill to derive KEK with PBKDF2 and encrypt a sample piece of data using AES-256-GCM in a SvelteKit context.
