# Intro to Encryptor extension

### True Self-custodial communication encryption

Used by Immu3 stack-enabled end-users, the Encryptor extension adds a communication encryption layer currently unsupported by major Web3 wallets. It enables the ECDH key agreement protocol, creating an elliptic curve key pair and computing the shared secret key between the sender and receiver. Similar to a Web3 wallet, it allows users to save their private key seed phrases, which can be used to restore their Encryptor at any time or on any device.

**Note:** Encryptor is an open-source, self-custodial Chrome extension built with Vite, Vue, and Manifest v3. It enables end-to-end AES-256-GCM encryption of on-chain communications using user-owned private keys, providing advanced and highly secure encryption.
