encrypt-down is an encryption layer for LevelDB.
For LevelDB exist several persistence bindings. Amongst others bindings for IndexedDB.
By using encrypt-down it is possible to store lots (several MB) of sensitive user data securely (encrypted) in the browser across user sessions.
npm install @adorsys/encrypt-downWe need a JSON Web Key (JWK) or JSON Web Key Set (JWKS) as specified by RFC 7517.
const memdown = require('memdown')
const encryptdown = require('@adorsys/encrypt-down')
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) {
console.log(value)
