Angular Library for ECDH Encryption Service

This package provides a Angular injectible service EchdEncryptionService which implements client side of Elliptic Curve Diffie-Hellman (ECDH) key exchange algorithm using ZenRoom

How to use

To use this service inject this in your App for example:

import { EcdhEncryptionService } from '@nuagebiztech/ecdh-angular-service'


constructor(
    private encryptionService: EcdhEncryptionService,
    private http: HttpClient
  ) {}

To start using this service you must initialize this with corresponding ECDH encryption server endpoints for

1. [GET] Retrieving server's public key
2. [POST] Submitting Client's Unique ID and Public Key

Note: service with automatically generates a 16 digit random id for client

  public initializedService(): void {
    this.encryptionService
      .initialize(this.serverPublicKeyUrl, this.sharedKeyUrl)
      .subscribe((clientId) => {
        console.log(clientId)
        this.clientId = clientId;
      });
  }

Once the service is initialized you can call encryptMessage(<<message>>) to encrypt the message, or decryptMessage(<<message>>) to decrypt the message.
