Build a Zero Knowledge backend with Node.js
summary
Claims a working Zero Knowledge backend implemented as a REST API that never sees plaintext, stores and returns encrypted blobs, issues certificates and JSON Web Tokens, validates signatures and timestamps, and manages key distribution while client-side code does heavy crypto. Uses restify, node-forge, jsonwebtoken plus passport and a document DB (MongoDB/CouchDB). Encrypts data with symmetric keys wrapped by recipients’ public keys, supports serverless deployment, and functions as a simple REST ping‑pong with expiration and signature checks.
