Add-SSHKeyAndAlias

This PowerShell script for Windows allows you to add an SSH public key to a specified remote host and create an alias in the local SSH config file (~/.ssh/config), similar to the ssh-copy-id utility in Unix-like systems.

Prerequisites

• PowerShell 5.0 or higher
• SSH client installed
• SSH public key file (e.g., id_ed25519.pub)

Usage

1. Clone or download the script.

2. Open a PowerShell terminal and run:

.\Add-SSHKey.ps1 -U <username> -H <remote_host> -A <alias>

• <username>: Username for the remote host
• <remote_host>: IP address or hostname of the remote host
• <alias>: Alias to add to the local SSH config

Script Details

Parameters

• -U: Username for the remote host
• -H: IP address or hostname of the remote host
• -A: Alias to add to the local SSH config

Workflow

1. Validates the provided parameters.
2. Reads the SSH public key file (default: ~/.ssh/id_ed25519.pub).
3. Adds the public key to the remote host.
4. Adds an alias to the local SSH config file (~/.ssh/config).

Error Handling

The script checks for errors at each step and outputs error messages if any issues occur.
