A secure key/value storage using AES encryption for values using localStorage
for Deno.
First, you need to import the SecretStore. After that, you just need to pass
in the key that you wish to use to sign your data. Note: this only needs to be
16 characters. If you create a key longer than that, then it will just truncate
the rest off. If you create a key shorter than that, then it will repeat the
characters of your key and push them to the front of the string until it is 16
characters.
import { SecretStore } from "https://deno.land/x/secret_store/mod.ts";
const store = new SecretStore({ key: "myawesomekey" });
await store.setItem("password", "my-secret-password");
// This is the encrypted value that any other application can access.
localStorage.getItem("password"); // d2eedcad9e0c285cb95d3c04381c60ae3ad99077642aecdb4c0781c2c0b8032b0e3ffac399060f803d86296a9c7d3d90
// The `SecretStore` automagically decrypts the data using AES and your key.
await store.getItem("password"); // my-secret-passwordYou can also pass in an iv into the SecretStore constructor which will be
the initializer vector used in the encryption/decryption.
The API matches completely to the localStorage object, except that the getItem and setItem properties are asynchronous to allow for the cryptographic algorithms to run.
