How do I access my SSH public key?
GitSshRsaGit Problem Overview
I've just generated my RSA key pair, and I wanted to add that key to GitHub.
I tried cd id_rsa.pub
and id_rsa.pub
, but no luck. How can I access my SSH public key?
Git Solutions
Solution 1 - Git
cat ~/.ssh/id_rsa.pub
or cat ~/.ssh/id_dsa.pub
You can list all the public keys you have by doing:
$ ls ~/.ssh/*.pub
Solution 2 - Git
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.
Solution 3 - Git
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.
Solution 4 - Git
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
Solution 5 - Git
Mac, Ubuntu, Linux compatible machines, use this command to print public key, then copy it:
$ cat ~/.ssh/id_rsa.pub
Solution 6 - Git
Here's how I found mine on OS X:
- Open a terminal
- (You are in the home directory)
cd .ssh
(a hidden directory) - pbcopy < id_rsa.pub (this copies it to the clipboard)
If that doesn't work, do an ls
and see what files are in there with a .pub
extension.
Solution 7 - Git
On terminal cat ~/.ssh/id_rsa.pub
explanation
- cat is a standard Unix utility that reads files and prints output
- ~ Is your Home User path
- /.ssh - your hidden directory contains all your ssh certificates
- id_rsa.pub OR id_dsa.pub are RSA public keys, (the private key located on the client machine). the primary key for example can be used to enable cloning project from remote repository securely to your client end point.
Solution 8 - Git
After you generate your SSH key you can do:
cat .ssh/id_rsa.pub |pbcopy
which will copy your ssh key into your clipboard.
Solution 9 - Git
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 . $profile
to load the functions. Then from now on all you will need to do is run sshkey
, and then paste the key into wherever you need via the clipboard.
Solution 10 - Git
If you're using windows, the command is:
type %userprofile%\.ssh\id_rsa.pub
it should print the key (if you have one). You should copy the entire result. If none is present, then do:
ssh-keygen -t rsa -C "[email protected]" -b 4096
Solution 11 - Git
Open your id_dsa.pub or some_name.pub file with gedit and copy-paste the contents!
Just use:
~/.ssh$ gedit some_name.pub
Solution 12 - Git
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.
Solution 13 - Git
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
Solution 14 - Git
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
Solution 15 - Git
It can be found on this path (default path):
/Users/john/.ssh
john
is your Mac username.
Solution 16 - Git
In UBUNTU +18.04
ssh-keygen -o -t rsa -b 4096 -C "email@example.com"
And After that Just Copy And Paste
cat ~/.ssh/id_rsa.pub
or
cat ~/.ssh/id_dsa.pub
Solution 17 - Git
> Open terminal > nano ~/.ssh/id_rsa.pub
Solution 18 - Git
Just to give a new perspective to that question, if you use github, you could find your public key at: https://github.com/${USERNAME}.keys
Solution 19 - Git
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.
Solution 20 - Git
I use Git Bash for my Windows.
$ eval $(ssh-agent -s) //activates the connection
- some output
$ ssh-add ~/.ssh/id_rsa //adds the identity
- some other output
$ 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.
Solution 21 - Git
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.
Solution 22 - Git
id_rsa.pub
is not a directory so you can not use cd
to open it.
instead you can use the command cd ~/.ssh
to access the folder containing your keys, then use cat id_rsa.pub
, nano id_rsa.pub
or gedit id_rsa.pub
to access the key file.
Solution 23 - Git
ssh-add
is used to show the public key.
man ssh-add
-L Lists public key parameters of all identities currently repre‐
sented by the agent.
On my Linux system I copy it using xclip
ssh-add -L | xclip
