====== Add a public SSH key to your instance  ======
~~NOTOC~~
You can register a public key during the creation of your instance for SSH key authentication during SFTP and Git access. 
**Please note that this is not available  for SSH console connection.**

To do this:

===== Step 1: Generate the keys =====
  * **Linux :** You can use the following OpenSSH tools (ssh-keygen)  command (available on Linux) : 
<code>ssh-keygen -t rsa -b 2048 </code>

  * ** Windows :** You can use the Putty generator 'PuttyGen' available on this [[http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html|page]]

===== Step 2: Add your public key =====

====== Remove a public SSH key from your instance  ======

 1. Login to your instance via [[en:simple:sftp|SFTP]]

 2. Navigate to the folder named '.ssh' located at the root of your SFTP directory listing

 3. To remove all SSH public keys simply delete the file 'authorized_keys'. Alternatively, you can edit the file and remove only the SSH public keys that you wish.
