## 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. ```js 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�£û���À∏wK=ú©ÒF)cîø…Z˘∑?c˘�Ë$s ``` Later in your app you can decrypt using your .dat file generated earlier and compare hashes ```js safe.decryptAsync()) //698fc0a07w63a530f66a65d0470ff37b725ec16062bd060bcf8a4a645da27885 ``` Youc can also sign your hashes and subsequently verify them. ```js 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.
