: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.

By using encrypt-down it is possible to store lots (several MB) of sensitive user data securely (encrypted) in the browser across user sessions.

``bash
npm install @adorsys/encrypt-down
`

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

`js
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)
// eyJlbmMiOiJBMjU2R0NNIiwiYWxnIjoiZGlyIiwia2lkIjoialpESEVqN0ZhR3N5OHNUSUZLRWlnejB4TjFEVWlBZWp0S1ZNcEl2Z3dqOCJ9..LLeRPtRCpn-Zie6-.zZc0LQ_vvHCppRAaC5fxw4yJ0041l6mGOSgLDVnaPagSv_3Khp8a8lyAo9utHQKpVX6RNVaVPBQQxJpkw_Zyljeg7L-O_Nc3N2Hi_904qE6_zwORqQRc.R0JhfgTHIcD_93kXzZ8BrA
