Encryptor is a Chrome extension developed by 4thTech that adds support for the encryption layer currently not supported in major Web3 wallets. This free extension enables the Elliptic-Curve Diffie-Hellman key agreement protocol, allowing users to create an elliptic curve key pair and compute the shared secret key of the receiver/sender.

The main purpose of Encryptor is to enable end-to-end encrypted communication within on-chain emailing, messaging, and data file transfers. With this extension, users can securely communicate and transfer sensitive information over the blockchain. The extension is open-source and fully self-custodial, ensuring that users have complete control over their data and encryption keys.
