aenigma

User-friendly AngularJS encryption module utilizing the Web Cryptography API and providing an extensible secure secret storage mechanism.

Getting Started

Installation

Install through npm:

npm install --save aenigma

Then include in your apps module:

import { NgModule } from '@angular/core';
import { AenigmaModule } from 'aenigma';

@NgModule({
  imports: [
    AenigmaModule.forRoot()
  ]
})
export class MyModule {}

Finally use in one of your apps components:

import { Component } from '@angular/core';

@Component({
  template: '<hello-world></hello-world>'
})
export class MyComponent {}

You may also find it useful to view the demo source.

Installation (without a module bundler)

<script src="node_modules/aenigma/bundles/aenigma.umd.js"></script>
<script>
    // everything is exported aenigma namespace
</script>

Usage

Set up the desired AenigmaStorageProvider implementation

@NgModule({
  imports: [
    AenigmaModule.forRoot()
  ],
  providers: [
    AenigmaLocalStorageProvider
  ]
})

Inject the AenigmaStorageProvider implementation into your component

constructor(private _encryptedStorageProvider: AenigmaLocalStorageProvider) { }

In your component create your Aenigma object

constructor(private _encryptedStorageProvider: AenigmaLocalStorageProvider) {

  Aenigma.create().subscribe(
    (aenigma: Aenigma) => {
      this._aenigma = aenigma;
    },
    error => {
      console.error(error);
    }
  );
}

Use the Aenigma object to initialize the AenigmaStorageService object

constructor(private _encryptedStorageProvider: AenigmaLocalStorageProvider) {

  Aenigma.create().subscribe(
    (aenigma: Aenigma) => {
      this._aenigma = aenigma;
      this._encryptedStorage = new AenigmaStorageService(
        this._aenigma,
        this._encryptedStorageProvider
      );
    },
    error => {
      console.error(error);
    }
  );
}

Use the Aenigma object to encrypt/decrypt data

this._aenigma
  .encrypt(plaintext)
  .subscribe((encrypted: EncryptedValue) => {
    console.log(encrypted.stringify());
  });

this._aenigma
  .decrypt(EncryptedValue.parse(cipher))
  .subscribe((decrypted: string) => {
    this._plaintext = decrypted;
  });

Use the AenigmaStorageService implementation to store/retrieve encrypted data

this._encryptedStorage
  .store('supersecret', 'secret_id')
  .subscribe((encrypted: EncryptedValue) => {
    console.log(encrypted.stringify());
  });

this._encryptedStorage
  .retrieve('secret_id')
  .subscribe((plaintext: string) => {
    console.log(plaintext);
  });
