NSSH

NSSH is a SSH Keys Manager for node.js command-line interfaces.
It can generate a ssh key and set ssh key config and copy the public key to a remote host with one commond.
then you can use ssh login with name, no need for passwords. 
Inspired by TimothyYe/skm , which is written in go language.

Features

* generate a ssh key and set ssh key config and copy the public key to a remote host with one commond
* Manage all your SSH keys by alias names
* Choose and set a default SSH key
* Copy default SSH key to a remote host
* Rename SSH key alias name

Installation

npm install nssh -g

Usage

$ nssh

Usage: nssh <command> [options]

Options:

    -V, --version      output the version number
    -v, --version      get version
    -t, --type <n>      0:Only create a new ssh key
                        1:Create a new ssh key and set ssh key config
                        2:Create a new ssh key and copy new ssh key to remote host
                        3:Create a new ssh key and copy new ssh key to remote host and set ssh key config

    -H --host [value]  Remote host address, you can include the usename and port, E.g: root@192.168.0.168:22
    -u --user [value]  Remote host of username, default root
    -p --port [value]  Remote host of port, default 22
    -N --new_passphrase [value]  Generate ssh key's new_passphrase
    -h, --help         output usage information


Basic Examples:

    # Initialize SSH keys store
    $ nssh init

    # List all the store SSH keys
    $ nssh ls

    # Create a new ssh key
    $ nssh create node0

    # Create a new ssh key and set its config
    $ nssh create node1 -t 1 -H root@192.168.0.2

    # Create a new ssh key for github and set its config
    $ nssh create github.com -t 1 -H liuyt@github.com

    # Create a new ssh key and copy public key to a remote host
    $ nssh create node1 -t 2 -H root@192.168.0.2

    # Create a new ssh key and set its config and copy public key to a remote host
    $ nssh create node1 -t 3 -H root@192.168.0.2

    # Copy ssh public key to a remote host
    $ nssh copy node1 root@192.168.0.2

    # Remove ssh key
    $ nssh rm default

    # Rename ssh key
    $ nssh rn default new

    # Switch to use the specified SSH key
    $ nssh use default

For the first time use

$ nssh init
✔ ssh key store initialized!
sh key store location is:C:\Users\liuyt\.nssh\

NOTE: If you already have id_rsa & id_rsa.pub key pairs in $HOME/.ssh, NSSH will move them to $HOME/.nssh/default

Create a new SSH key

$ nssh create work1 -t 3 -H root@139.196.39.155
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\liuyt\.nssh\.tmp\id_rsa.
