    NOTES:

    • Accessing HPC must be passwordless unless you have a passphrase during the generating of keys.
    • If you want to use your key (generated using PuTTY) in OpenSSH, check this tutorial on converting PuTTY (.ppk) key to SSH Key.
    • You cannot use your OpenSSH keys to PuTTY and vice versa.
