# Ethereum Private Message Using Wallet Encryption Web App
|
||||
|
||||
**Demonstrates**:
|
||||
|
||||
- Private Messaging
|
||||
- React/TypeScript
|
||||
- Waku Light Push
|
||||
- Signature with Web3
|
||||
- Asymmetric Encryption
|
||||
- Usage of [`eth_decrypt`](https://docs.metamask.io/guide/rpc-api.html#eth-decrypt) Wallet API
|
||||
|
||||
This dApp demonstrates how to send and received end-to-end encrypted messages
|
||||
using the encryption API provided by some Web3 Wallet provider such as [Metamask](https://metamask.io/).
|
||||
|
||||
The sender only needs to know the Ethereum address of the recipient.
|
||||
The recipient must broadcast his encryption public Key as a first step.
|
||||
|
||||
To run a development version locally, do:
|
||||
|
||||
```shell
|
||||
git clone https://github.com/status-im/js-waku/ ; cd js-waku
|
||||
npm install # Install dependencies for js-waku
|
||||
npm run build # Build js-waku
|
||||
cd examples/eth-pm-wallet-encryption
|
||||
npm install # Install dependencies for the web app
|
||||
npm run start # Start development server to serve the web app on http://localhost:3000/js-waku/eth-pm-wallet
|
||||
