怎么上手

由 README 提炼，执行前请确认
原文 
从 https://github.com/PurpleI2P/i2pd/releases/latest 下载预编译包或二进制文件安装；源码构建方式见 https://i2pd.readthedocs.io/en/latest/
硬件要求按 README 说明

README 未说明具体硬件要求，仅列出支持的系统与平台（GNU/Linux、Windows、macOS、FreeBSD、Android、iOS、Docker、Snap）

I2P 匿名网络的 C++ 全功能客户端守护进程，用来搭建端到端加密、不暴露真实 IP 的匿名通信

轻量级 C++ 实现的 I2P 匿名网络客户端，提供端到端加密通信，可替代官方 Java 版，适合在资源受限设备上搭建隐私网络。

核心能力

  • 实现 I2P 匿名网络层，通信端到端加密且不暴露真实 IP
  • 提供分布式匿名网络框架，支持 P2P 与客户端-服务器类应用
  • 体积小、依赖简单、性能快
  • 为安全应用开发者提供丰富的 API 集合
  • 支持 Linux、Windows、macOS、FreeBSD、Android、iOS 及 Docker/Snap 部署

容易踩的坑

README 建议优先用预编译包，源码构建需按对应操作系统文档操作；Android 与 Qt GUI 版本在独立仓库 i2pd-android、i2pd-qt 中；项目不接受 LLM/AI 生成的 PR 与 issue 文本

内容由模型根据 README 生成，可能不完整或不准确，以官方文档为准。看原文 README

    i2pd

    Русская версия

    i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.

    I2P (Invisible Internet Protocol) is a universal anonymous network layer.
    All communications over I2P are anonymous and end-to-end encrypted, participants don't reveal their real IP addresses.

    I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers).

    I2P allows people from all around the world to communicate and share information without restrictions.

    Features

    • Distributed anonymous networking framework
    • End-to-end encrypted communications
    • Small footprint, simple dependencies, fast performance
    • Rich set of APIs for developers of secure applications
