# Encryptor Setup User Guide

### Encryptor Setup

Used to enable the Elliptic-Curve Diffie-Hellman key agreement protocol, the Encryptor Extension adds the Email & Messaging encryption layer currently not available in major Web3 wallets. It creates an elliptic curve key pair and computation of the shared secret key of the receiver/sender. The extension is fully self-custodial and enabled by choice, while its UI is simple and user-friendly. 

Steps:

* ⚙️ Download, Install the [Encryptor Extension](https://chrome.google.com/webstore/detail/encryptor/feolajpinjjfikmmeknkdjbllbppojij?authuser=3\&hl=en-GB) from the Google Chrome Store
* 🔧 Set your Encryptor password and save your seed words or restore your previous Encryptor installation by pasting restore seed word.

Complete your in-app Encryptor Extension registration by creating a transaction on the smart contract. This step is essential to activate the extension’s full capabilities and adds its visibility on the blockchain making the connection between the sender & recipient possible.

Register the Encryptor:

* ⛓️ "**Register Encryptor**" and confirm the transaction with your wallet
