How do I access my SSH public key?

Question

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?

Answer 1

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

Answer 2

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.

Answer 3

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

Answer 4

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 you can paste it wherever you need.

Answer 5

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.

or

         cat ~/.ssh/id_dsa.pub
