Generating SSH keys

SSH keys serve as a way to identify users to an SSH server without involving passwords.

In order to generate a NEW key follow these steps:


  • Check for existing SSH keys on your computer.
$ ls -la ~/.ssh
# Lists the files in your .ssh directory , if they exist

#  By default, the filenames of the public keys are one of the following:
  • An SSH key pair can be generated by running the ssh-keygen command:
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ ssh-keygen -t rsa -b 4096 -C ""

Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/
The key fingerprint is:
The key's randomart image is:
+--[RSA  4096]---+
