You will now see the key pair in the hidden `.ssh` directory of your home as files `~/.ssh/id_ed25519` and `~/.ssh/id_ed25519.pub` (or `~/.ssh/id_rsa` and `~/.ssh/id_rsa.pub`).

#### 2.2.2 Step 2: Transfer the public key
You can now send us the **public** key (`id_ed25519.pub`), either as a file or by copy-paste of the public key file contents:
```
cat ~/.ssh/id_ed25519.pub
```
**Please send the public key to:****hpc-mgr@uni-koeln.de**
On Ramses, the remote machine, your public key (\*.pub) will be a single-line item in your `~/.ssh/authorized_keys` file. Together with your matching local private key, it enables SSH authentication without password request.
Now the newly generated SSH public key needs to be transferred to your Ramses home directory.
To this end, we have set up a dedicated [Ramses key upload website](https://ramses-umc.itcc.uni-koeln.de/web-sshkey/login). Log in with your uniKIM credentials (username and password) and upload your public key. It will then be installed in your `~/.ssh/authorized_keys` file on Ramses and enable SSH authentication without a password request when used with your matching private key on the local host.
#### 2.2.3 Step 3 (optional): Wanna pass on the passphrase? - Call your agent!
`ssh-agent` is a program which can automatically do your authentication when logging in to a remote machine via SSH. Thus, to avoid providing the passphrase during multiple subsequent sessions, you can load the private key into memory using the SSH agent.
