Description
An extension using blockchain technology for peer-to-peer encryption of emails mail encrypt tool based on blockchain technology By using blockchain wallet technology, email content is encrypted in a peer-to-peer manner. Users can achieve offline encryption of data and secure wallet migration by creating a unique mnemonic phrase. Users can achieve secure email encryption through three steps: 1. **Create a blockchain wallet using a mnemonic phrase**, and encrypt the wallet's private key using a local password. This process is completely offline and does not require internet services. *(Note: The blockchain wallet created in this process is not for storing cryptocurrencies, but for creating an email blockchain address.)* 2. **Bind the user's email address and blockchain email address** during the plugin's decryption process, using blockchain signature technology. 3. **Notify your email contacts to create and bind their blockchain email address**. When composing an email, simply enter your contact's email address, and the plugin will automatically query the blockchain address associated with that email address and implement peer-to-peer encryption. **Advantages of this plugin**: 1. **No account password storage on any server**. No account recovery features are provided, so please keep your mnemonic phrase safe. 2. **The plugin will not store or upload any of the user's email content**. After an email is encrypted, it can only be decrypted by the designated recipient through the plugin. The email content is absolutely secure when transmitted or stored through any untrusted network or server, as it is transmitted and stored in encrypted form. Email service providers cannot identify or spy on the original email content. 3. **Support for secondary development**. This plugin provides content encryption services for third-party email systems, offering equivalent functionality. After installing this plugin, developers can provide users with peer-to-peer encryption services. 4.**The plugin supports encryption and decryption of attachment contents**. For non-large attachments, it allows joint encryption of both the email body and attachments. The attachments can only be decrypted after decrypting the email content, and the decryption can only be performed within the email system. Attachments outside the email environment cannot be decrypted.
