SSH Key-Pair Manager CLI

This is a Go-based CLI tool that helps you manage multiple SSH key-pairs for different companies or Git repositories. It allows you to switch between SSH certificates, generate new key-pairs, and manage your SSH setup efficiently.

Features

  • List available SSH key-pair and switch between them.
  • Generate new key-pairs with different algorithms.
  • Manage folders for storing key-pairs.
  • Uses default values for algorithms and comments if not provided.

Installation

  1. Clone the repository and navigate to the project folder:
git clone git@github.com:DavidGarciaCat/ssh-key-manager-cli.git
cd ssh-key-manager-cli
  1. Build the binary:

Run the following command to build the Go binary:

go build -o ssh-manager main.go
  1. Install the binary globally:

To make the ssh-manager available globally, move it to a directory in your $PATH (e.g., /usr/local/bin):

sudo mv ssh-manager /usr/local/bin/

Now you can run the ssh-manager from any location in your terminal.

Usage

  1. Launch the SSH Key Manager CLI:
ssh-manager
