For LevelDB exist several persistence bindings. Amongst others bindings for [IndexedDB](https://developer.mozilla.org/de/docs/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. ### Installation ```bash npm install @adorsys/encrypt-down ``` ### Usage We need a JSON Web Key (JWK) or JSON Web Key Set (JWKS) as specified by [RFC 7517](https://tools.ietf.org/html/rfc7517). ```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 }) db.get('key', { asBuffer: false }, function (err, value) { console.log(value) // { awesome: true } }) }) ``` ### Browser Support [![Sauce Test Status](https://saucelabs.com/browser-matrix/adorsysbot.svg)](https://saucelabs.com/u/adorsysbot) ## API ### `const db = require('@adorsys/encrypt-down')(db[, options])` - `db` must be an [`abstract-leveldown`](https://github.com/level/abstract-leveldown) compliant store - `options`: - `jwk`: a JSON Web Key (JWK) or JSON Web Key Set (JWKS) as specified by [RFC 7517](https://tools.ietf.org/html/rfc7517) ## Credits Made with :heart: by [radzom](https://github.com/radzom) and all these wonderful contributors ([emoji key](https://github.com/kentcdodds/all-contributors#emoji-key)):
