通过NSSH可以管理SSH密钥，一条命令，生成密钥，拷贝到服务器，添加配置，通过别名进行无密码登陆。
测试了Windows和ubuntu，没有mac电脑，没有测试mac，如果有BUG大家给我留言，谢谢。
* 一键创建密钥，并拷贝的远程主机，通过别名直接登录
* 对SSH密钥可以创建，删除，查看列表
* 通过别名管理密钥
* 选择和设置默认密钥
* 拷贝密钥到远程主机
* 对SSH 密钥别名进行重命名
npm install nssh -g
$ nssh
Usage: nssh <command> [options]
Options:
-V, --version output the version number
-h, --help output usage information
Commands:
init 初始化SSH key库
ls 查看SSH key列表
use <name> 切换SSH key
rm <name> 删除SSH key
rn <name> <new> 修改SSH key名称
create <name> 创建SSH key
copy <name> <host> 创建SSH key
help [cmd] display help for [cmd]
$ nssh init
✔ 密钥库初始化完成
密钥库地址为：C:\Users\liuyt\.nssh\
注意：如果您在$home/.ssh已经有id_rsa、id_rsa.pub密钥对,那么初始化将会将其移动到$HOME/.nssh/default
$ nssh create work1 -t 3 -h [email protected]
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.
Your public key has been saved in C:\Users\liuyt\.nssh\.tmp\id_rsa.pub.
The key fingerprint is:
SHA256:IoWtg5M1+7VUANVB/JdU2EYVGjzMh5he/iSkwNfjRp4 liuyt@DESKTOP-48BGCR8
The key's randomart image is:
+---[RSA 2048]----+
| .o++o.B..**|
| o +o+ %=.o|
| + o =.Oo=o |
| + = . o.Eo. |
| + = . S ..+ |
| . + + . . |
| . . |

+----[SHA256]-----+
密钥已生成
ssh-copy-id: INFO: Source of key(s) to be installed: "C:\Users\liuyt\.nssh\.tmp\id_rsa.pub"
ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]'s password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh '[email protected]'"
and check to make sure that only the key(s) you wanted were added.
密钥拷贝完成，主机：[email protected]
配置添加完成，配置地址：C:\Users\liuyt\.ssh\config
✔ 密钥创建成功

$ nssh create
Usage: nssh-create <name>
Options:
-t --type <n> 0:仅创建SSH key 1:创建SSH key并生成配置 2:创建SSH key 并拷贝到远程主机 3、创建SSH key，生成配置并拷贝到远程主机
-h --host [value] 主机地址
-h, --help output usage information
Examples:
# 通过nssh创建密钥
$ nssh create node0
# 通过nssh创建密钥并生成配置
$ nssh create node1 -t 1 -h [email protected]
# 通过nssh创建密钥并生成github配置
$ nssh create github.com -t 1 -h [email protected]
# 通过nssh创建密钥并拷贝到192.168.0.2
$ nssh create node1 -t 2 -h [email protected]
# 通过nssh创建密钥,生成配置并拷贝到192.168.0.2
$ nssh create node1 -t 3 -h [email protected]
$ nssh ls
✔ 找到2个密钥
-> test (current)
test2
$ nssh use test2
✔ 当前使用的密钥：test2
$ nssh ls
✔ 找到2个密钥
test
-> test2 (current)
$ nssh rn test2 nsew
✔ test2重命名为：new
$ nssh ls
✔ 找到2个密钥
-> new (current)
test2
$ nssh rm new
? 确定要删除 new 吗？ (Y/n)
? 确定要删除 new 吗？ Yes
✔ 删除密钥new完成
$ nssh ls
✔ 找到1个密钥
test2
$ nssh copy
Usage: nssh-copy <name> <host>
Options:
-h, --help output usage information
Examples:
# 通过nssh拷贝密钥到远程主机
$ nssh copy node1 [email protected]
NSSH的大部分思路来源与SKM，参考了大部分代码，只是通过Node实现了而已,在此特别声明，非常感谢。
