SSH Keypair Generator

This Go utility automatically generates a cryptographically stable RSA SSH key pair and outputs the public and private keys.

Installation

To install and use the SSH keygen utility, follow these steps:

1. Install Go and set up your Go environment. See the Go installation guide for more information.

2. Clone this repository:

   git clone https://github.com/sv222/ssh-keypair-gen.git
   cd ssh-keypair-gen

3. Build the binary:

   go build -o ssh-keypair-gen

Usage

Local installation

1. Run the binary with the desired flags. For example, to generate a 4096-bit key and save the private key as mykey.pem and the public key as mykey.pub, run the following command:

   ./ssh-keypair-gen --size 4096 --private-key mykey.pem --public-key mykey.pub

You can choose not to pass values, then the names will be given by default and the files will be saved in the current folder.

./ssh-keypair-gen

Docker installation

1. Build the Docker image:

   docker build -t ssh-keypair-gen .

2. Run the Docker container with the desired flags. For example, to generate a 4096-bit key and save the private key as mykey.pem and the public key as mykey.pub, run the following command:

   docker run -v $(pwd):/keys ssh-keypair-gen --private-key /keys/id_rsa.pem --public-key /keys/id_rsa.pub

The above command uses the -v flag to mount the current directory as a volume inside the container, and the -w flag to set the working directory inside the container to /app, which is where the binary and output files are located.

Replace "my-go-app" with the name you gave to the Docker image when you built it.
