 If you have never created SSH keys before we have made this helper script that will do it for you. Simply run this command in a terminal that is logged into UPPMAX:
 
 ```bash
-rm ~/.ssh/id_ed25519_pdc
+darsync sshkey
 ```
 
 and it will create an SSH key that can be used when running Darsync. Since Darsync runs as a SLURM job, it has to be unencrypted (i.e. not require a password to use it). This is not the recommended way to store your SSH keys, so please delete this SSH key once your data transfer is completed. If you still need a SSH key on UPPMAX to connect to Dardel, please create a new one with a password and add that one to the PDC login portal, and delete the key you created for the data transfer.
