A gallery script for photos stored in your Akord Vault.

Creating and Deploying a Vault in Akord

Akord provides a decentralized platform for users to securely store and share their digital assets. One of its features is the ability to create a Vault, which can be thought of as a secure container for your digital files. In this article, we'll walk you through the steps to set up a Vault in Akord, upload files, and publish a manifest to make your content accessible via the Permaweb.

Step 1: Setting Up Your Vault

  1. Navigate to Akord: Open your web browser and head to v2.akord.com.
  2. Create a New Public Vault: Once on the platform, initiate the process to create a new 'public' vault. This vault will be accessible to anyone on the permaweb, making it perfect for sharing content like photo galleries.

Step 2: Uploading Your Content

Saving Web Crypto Keys using indexedDB

This is a working example on how to store CryptoKeys locally in your browser. We are able to save the objects, without serializing them. This means we can keep them not exportable (which might be more secure?? not sure what attack vectors this prevents).

To try out this example, first make sure you are in a browser that has support for async...await and indexedDB (latest chrome canary with chrome://flags "Enable Experimental Javascript" works). Load some page and copy and paste this code into the console. Then call encryptDataSaveKey(). This will create a private/public key pair and encrypted some random data with the private key. Then save both of them. Now reload the page, copy in the code, and run loadKeyDecryptData(). It will load the keys and encrypted data and decrypt it. You should see the same data logged both times.
