So, where are my SSH keys?
SKM will create SSH key store at $HOME/.skm
and put all the SSH keys in it.
NOTE: If you already have id_rsa & id_rsa.pub key pairs in $HOME/.ssh
, SKM will move them to $HOME/.skm/default
NOTE: Currently ONLY RSA and ED25519 keys are supported!
skm create prod -C "[email protected]"
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/timothy/.skm/prod/id_rsa.
Your public key has been saved in /Users/timothy/.skm/prod/id_rsa.pub.
...
✔ SSH key [prod] created!
% skm ls
✔ Found 3 SSH key(s)!
-> default
dev
prod
% skm use dev
Now using SSH key: dev
You can just type skm use
, then a prompt UI will help you to choose the right SSH key:
% skm display
Or display specific SSH public key by alias name:
% skm display prod
% skm delete prod
Please confirm to delete SSH key [prod] [y/n]: y
✔ SSH key [prod] deleted!
% skm cp [email protected]
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/timothy/.skm/default/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/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.
✔ Current SSH key already copied to remote host
% skm rn test tmp
✔ SSH key [test] renamed to [tmp]
Backup all your SSH keys to $HOME directory by default.
% skm backup

a ./test
a ./default
a ./dev
a ./dev/id_rsa
a ./dev/id_rsa.pub
a ./default/id_rsa
a ./default/id_rsa.pub
a ./test/id_rsa
a ./test/id_rsa.pub
✔ All SSH keys backup to: /Users/timothy/skm-20171016170707.tar
% skm restore ~/skm-20171016172828.tar.gz

✔ All SSH keys restored to /Users/timothy/.skm
Edit and place a executable file named hook
at the specified key directory, for example:
~/.skm/prod/hook
This hook file can be both an executable binary file or an executable script file.
SKM will call this hook file after switching default SSH key to it, you can do some stuff in this hook file.
