Using SSH key pairs (e. Secure Shell) is a way of logging into ssh account using a cryptographic key rather than a password.
When new user requests access via service portal to our HPC centre it’s mandatory to provide a paired public key to complete the user creation process.
Example of creating a key pair with bash:
- $ssh-keygen -t rsa
- Enter file in which to save the key (/home/user/.ssh/id_rsa):
- Enter passphrase (empty for no passphrase):
- Enter same passphrase again:
- Your identification has been saved in /home/user/.ssh/id_rsa.
- Your public key has been saved in /home/user/.ssh/id_rsa.pub.
- $cat /home/user/.ssh/id_rsa.pub
- Copy and pase the id_rsa.pub key into the service portal order.
