  1. Log-in to the Rapid Access Cloud dashboard at https://cloud.cybera.ca.

  2. In the left-hand panel under “Compute”, click “Access & Security”.

  3. Click the “Key Pair” tab, then click “+Create Key Pair”.

  4. Enter a <key_pair_name>, then click “Create Key Pair”. The browser will automatically download a file named <key_pair_name>.pem.

  5. Move or save this file on your computer somewhere you will remember. It will be used when accessing instances created with this key pair.

     

Note

If this key file is saved to an operating system that uses file-system permissions (Unix, Linux, BSD, OSX) then make sure the permissions are set appropriately. Typically, the .ssh directory permissions ought to be set to 700 (drwx------) and the private key (*.pem) should be 600 (-rw-------). To change the permissions of the downloaded key to 600, do:

Code Block
$ chmod 600 /path/to/<key_pair_name>.pem
Warning

The private key generated in the step above is not recoverable if it is lost. It is highly recommended that a backup of the key is made and kept safe, ideally on a separate hard drive or USB key.

Info

About key pairs

Key pairs are a set of mathematically generated strings, one is the private key and the other is the public key. The key pairs that are used in the Rapid Access Cloud are ssh keys generated by the OpenStack dashboard, keeping the public key to be injected as needed into new instances, and the private key is the *.pem file automatically downloaded by the browser in the steps above. If you already have a key pair suited for use, import that key by following the steps in the Advanced Guide. 


A detailed explanation of public-key cryptography is out of the scope of this document; 
this will help you understand it better.
