SSH-Copy-ID for Windows is a command-line tool designed to simplify the process of copying SSH public keys to remote servers' authorized_keys files, specifically tailored for Windows systems. This utility mirrors the functionality of the Linux ssh-copy-id command, providing a seamless way to manage SSH authentication on Windows environments.

Key Features:

SSH Key Deployment: Easily copy SSH public keys to remote servers, enabling secure and passwordless access.
Customization Options: Support for custom SSH key files and ports, allowing flexibility in configuration.
Automatic Setup: Automatically creates the necessary .ssh directory and authorized_keys file on the remote server if they do not exist.
Duplicate Prevention: Detects and prevents duplicate keys from being added to the authorized_keys file, ensuring clean and efficient key management.
Cross-Platform Compatibility: Designed for Windows but compatible with SSH protocols used across various platforms.

Audience & Benefit:

Ideal for system administrators, developers, and IT professionals who manage SSH access on Windows systems. This tool streamlines the deployment of SSH keys, reducing manual configuration steps and potential errors. By automating key management, it enhances security, improves efficiency, and simplifies remote server administration. The tool can be installed via winget, ensuring a straightforward setup process for users familiar with package managers.

SSH-Copy-ID for Windows is a practical solution for anyone looking to simplify SSH authentication on Windows systems, offering a reliable and efficient alternative to manual key management.

SSH-Copy-ID for Windows

这是一个用Go语言编写的ssh-copy-id工具的Windows实现，用于将SSH公钥复制到远程服务器。

功能特性

支持指定自定义的SSH公钥文件
支持自定义SSH端口
自动创建远程服务器的.ssh目录和authorized_keys文件
去重处理，避免重复添加相同的公钥
跨平台支持（主要针对Windows）

安装

确保已安装Go 1.19或更高版本
克隆或下载此项目
在项目目录中运行：

go mod tidy
go build -o ssh-copy-id.exe main.go

使用方法

基本用法

# 使用默认公钥文件 (~/.ssh/id_rsa.pub)
ssh-copy-id.exe user@example.com

# 指定用户和主机
ssh-copy-id.exe myuser@192.168.1.100

高级用法

# 指定自定义公钥文件
ssh-copy-id.exe -i C:\Users\username\.ssh\mykey.pub user@example.com

# 指定自定义SSH端口
ssh-copy-id.exe -p 2222 user@example.com

# 组合使用选项
ssh-copy-id.exe -i ~/.ssh/custom_key.pub -p 2222 admin@server.example.com

命令行选项

-i <密钥文件>: 指定要复制的公钥文件路径 (默认: ~/.ssh/id_rsa.pub)
-p <端口>: 指定SSH端口 (默认: 22)
-h: 显示帮助信息

Windows SSH密钥位置

程序会自动检测以下位置的SSH公钥：

%USERPROFILE%\.ssh\id_rsa.pub (RSA密钥)
%USERPROFILE%\.ssh\id_ed25519.pub (Ed25519密钥)
%USERPROFILE%\.ssh\id_ecdsa.pub (ECDSA密钥)

如果没有找到SSH密钥，程序会给出生成密钥的提示。

生成SSH密钥

如果你没有SSH密钥，可以使用以下方法生成：

方法1: 使用提供的批处理脚本

generate-key.bat

方法2: 手动生成

# 生成RSA密钥 (推荐4096位)
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

# 或生成Ed25519密钥 (更现代，更安全)
ssh-keygen -t ed25519 -C "your_email@example.com"

密钥将保存在 %USERPROFILE%\.ssh\ 目录中。

安全性: 当前版本使用 ssh.InsecureIgnoreHostKey() 来忽略主机密钥验证。在生产环境中，建议实现proper host key verification。
密码输入: 密码输入是明文显示的。如果需要隐藏密码输入，可以集成 golang.org/x/term 包。
密钥格式: 确保你的公钥文件格式正确（通常以ssh-rsa、ssh-ed25519等开头）。
权限: 程序会自动设置远程服务器上.ssh目录和authorized_keys文件的正确权限。
