:closed_lock_with_key: encrypt-down :closed_lock_with_key:

encrypt-down is an encryption layer for LevelDB.

For LevelDB exist several persistence bindings. Amongst others bindings for IndexedDB.

So lots (several MB) of sensitive user data can be stored securely (encrypted) in the browser across user sessions.

Installation

npm install @adorsys/encrypt-down

Usage

We need a JSON Web Key (JWK) or JSON Web Key Set (JWKS) as specified by RFC 7517.

const memdown = require('memdown')
const encryptdown = require('./src')
const levelup = require('levelup')
const jwk = {
  kty: 'oct',
  alg: 'A256GCM',
  use: 'enc',
  k: '123456789abcdefghijklmnopqrstuvwxyz12345678'
}
const memdb = memdown()
const db = levelup(encryptdown(memdb, { jwk }))

db.put('key', { awesome: true }, function (err) {
  memdb._get('key', { asBuffer: false }, function (err, value) {
        value
        console.log(value)
        // eyJlbmMiOiJBMjU2R0NNIiwiYWxnIjoiZGlyIiwia2lkIjoialpESEVqN0ZhR3N5OHNUSUZLRWlnejB4TjFEVWlBZWp0S1ZNcEl2Z3dqOCJ9..LLeRPtRCpn-Zie6-.zZc0LQ_vvHCppRAaC5fxw4yJ0041l6mGOSgLDVnaPagSv_3Khp8a8lyAo9utHQKpVX6RNVaVPBQQxJpkw_Zyljeg7L-O_Nc3N2Hi_904qE6_zwORqQRc.R0JhfgTHIcD_93kXzZ8BrA
  })
  db.get('key', { asBuffer: false }, function (err, value) {
    console.log(value) 
    // { awesome: true }
  })
})

API

const db = require('@adorsys/encrypt-down')(db[, options])

• db must be an abstract-leveldown compliant store
• options:
  • jwk: a JSON Web Key (JWK) or JSON Web Key Set (JWKS) as specified by RFC 7517
