After you generate your SSH key you can do:
cat .ssh/id_rsa.pub |pbcopy
which will copy your ssh key into your clipboard.
Open terminal nano ~/.ssh/id_rsa.pub
Use:
# sudo su
# cd /home/user/.ssh
.ssh# gedit id_rsa.pub
Then copy the entire file without any spaces. Click your icon at the top right of the GitHub page, go to settings, and add ssh.
Paste the copy into the space. It may prompt for your GitHub password. Enter it. Save.
It can be found on this path (default path):
/Users/john/.ssh
john
is your Mac username.
On terminal cat ~/.ssh/id_rsa.pub
explanation
On a Mac, you can do this to copy it to your clipboard (like cmd + c
shortcut)
cat ~/Desktop/ded.html | pbcopy
pbcopy < ~/.ssh/id_rsa.pub
and to paste
pbpaste > ~Documents/id_rsa.txt
or, use cmd + v
shorcut
to paste it somewhere else.
~/.ssh
is the same path as /Users/macbook-username/.ssh
You can use Print work directory: pwd
command on terminal to get the path to your current directory.
On Mac/unix and Windows:
ssh-keygen
then follow the prompts. It will ask you for a name to the file (say you call it pubkey, for example).
Right away, you should have your key fingerprint and your key's randomart image visible to you.
Then just use your favourite text editor and enter command vim pubkey.pub
and it (your ssh-rsa key) should be there.
Replace vim with emacs or whatever other editor you have/prefer.
If you only have your private key available, you can generate the public key from it:
ssh-keygen -y
or
ssh-keygen -y -f path/to/private_key
Copy the key to your clipboard.
$ pbcopy < ~/.ssh/id_rsa.pub
# Copies the contents of the id_rsa.pub file to your clipboard
Warning: it's important to copy the key exactly without adding newlines or whitespace. Thankfully the pbcopy command makes it easy to perform this setup perfectly.
and paste it wherever you need.
More details on the process, check: Generating SSH Keys.
I use Git Bash for my Windows.
$ eval $(ssh-agent -s) //activates the connection
$ ssh-add ~/.ssh/id_rsa //adds the identity
$ clip < ~/.ssh/id_rsa.pub //THIS IS THE IMPORTANT ONE. This adds your key to your clipboard. Go back to GitHub and just paste it in, and voilá! You should be good to go.
If you're on Windows use the following, select all, and copy from a Notepad window:
notepad ~/.ssh/id_rsa.pub
If you're on OS X, use:
pbcopy < ~/.ssh/id_rsa.pub
Open your id_dsa.pub or some_name.pub file with gedit and copy-paste the contents!
Just use:
~/.ssh$ gedit some_name.pub
If you're using windows, the command is:
type %userprofile%\.ssh\id_rsa.pub
_x000D_
it should print the key (if you have one). You should copy the entire result. If none is present, then do:
ssh-keygen -t rsa -C "[email protected]" -b 4096
_x000D_
Here's how I found mine on OS X:
cd .ssh
(a hidden directory)If that doesn't work, do an ls
and see what files are in there with a .pub
extension.
In UBUNTU +18.04
ssh-keygen -o -t rsa -b 4096 -C "[email protected]"
And After that Just Copy And Paste
cat ~/.ssh/id_rsa.pub
or
cat ~/.ssh/id_dsa.pub
The following command will save the SSH key on the clipboard. You only need to paste at the desired location.
cat ~/.ssh/id_rsa.pub | pbcopy
If you are using Windows PowerShell, the easiest way is to:
cat ~/.ssh/id_<key-type-here>.pub | clip
That will copy the key to your clipboard for easy pasting.
So, in my instance, I use ed25519 since RSA is now fairly hackable:
cat ~/.ssh/id_ed25519.pub | clip
Because I find myself doing this a lot, I created a function and set a simple alias I could remember in my PowerShell profile (learn more about PowerShell profiles here. Just add this to your Microsoft.PowerShell_profile.ps1
:
function Copy-SSHKey {
Get-Content ~/.ssh/id_ed25519.pub | clip
}
Set_Alias -Name sshkey -Value Copy-SSHKey
Then, in a PowerShell console, run . $profile
to load the functions. Then from now on all you will need to do is run sshkey
, and then paste the key into wherever you need via the clipboard.
You may try to run the following command to show your RSA fingerprint:
ssh-agent sh -c 'ssh-add; ssh-add -l'
or public key:
ssh-agent sh -c 'ssh-add; ssh-add -L'
If you've the message: 'The agent has no identities.', then you've to generate your RSA key by ssh-keygen
first.
