Welcome to my my Blog … this time i try to write in English 
. Before you generate a new an ssh key to use for an authentication on github, cpanel hosting or another project, you can check for existing SSH Keys on your pc or laptop. What i am talking here is how to generate SSH Keys On linux
Checking for existing SSH Key >> Open Terminal
ls -al ~/.ssh
# If they exist, it will shows list the file in your .ssh
Example:
-rw------- 1 3326 Mei 20 20:42 id_rsa
-rw-r--r-- 1 754 Mei 20 20:42 id_rsa.pub
Let’s Create A new SSH Key via Command Line
So Now.. if You dont' have an SSh Key on your Komputer , let’s generate a new SSH Key.
Open Terminal
ssh-keygen -t rsa -b 4096 -C "your _email@example.com"
# Creates new ssh key, by using the provided email as a label
# in the example above, a 4096 bit RSA key.
Generating public/private rsa key pair
Than press enter to the deafult location of your key
Enter a file in which to save the key (users/you/.ssh/id_rsa): [Press Enter]
# You can modify a file in which to save the key example: (users/you/id_rsa_myproject)
# You can generate more than one SSH Keys by modifying it
Now you can insert a secure passphrase/Password
Enter passphrase/Password (empty fo no passphrase): [Type passphrase]
Enter same passphrase again: [Type same passphrase again]
Adding SSH key to the ssh-agent
eval "$(ssh-agent -s)"
Example Agent pid 58522
Than type this to save ssh key :
ssh-add ~/.ssh/id_rsa
# Your identification has been saved in id_rsa
# Your public key has been saved in id_rsa.pub
The key finger print is d0:d6:c7:ec ..... bla...bla
How to open your Public key ?
cat ~/.ssh/id_rsa.pub
That’s All 
…. now if you have project on github you can put them there… by opening profile >> settings >> SSH and GPG keys
Note: reference >> github
