Generate and encrypt payloads

This is a module for generating, encrypting and decrypting payloads for your app.

Usecases

Your app (eg Electron) needs custom frontend updates that could be applied seamlessly.

const Vault = require('encrypt-payloads')

const safe = new Vault('vault.dat', 'your-password')

safe.hashElement(FOLDER_PATH) // 698fc0a07w63a530f66a65d0470ff37b725ec16062bd060bcf8a4a645da27885
  .then(hash => safe.encryptAsync(hash)) //‘!ÓN�`›a¡xRÁnz£ûÀ∏wK=ú©ÒF)cîø…Z˘∑?c˘�Ë$s

Later in your app you can decrypt using your .dat file generated earlier and compare hashes

safe.decryptAsync()) //698fc0a07w63a530f66a65d0470ff37b725ec16062bd060bcf8a4a645da27885

Youc can also sign your hashes and subsequently verify them.

safe.hashElement(FOLDER_PATH)
  .then(r => safe.generateKeysAndSign(r.hash, 'my-key'))
  .then(r => safe.verifySignature()) // true

This would mean that the payload hash the same hash, so the there is no need for update, otherwise you can apply the update knowing the payload has been updated.
