SSH Keys

What is an SSH key?

An SSH key is a pair of cryptographic keys (private and public) used for secure passwordless server login.

Public key is added to your account and then attached to an instance.
Private key is stored by you and used for authentication.

Benefits: stronger security, no password entry, easier automation.

Внимание

Never share your private SSH key. Treat it like sensitive payment credentials.

Create your first SSH key

Generate a key pair:
```
ssh-keygen
```

Enter file name for keys (or press Enter to keep default), then optionally set passphrase:

Enter file in which to save the key (/root/.ssh/id_rsa): <File name>
Enter passphrase (empty for no passphrase): <Passphrase>
Enter same passphrase again: <Passphrase again>

Read the public key:
```
cat /root/.ssh/id_rsa.pub
```
Copy the value starting with ssh-rsa, then open SSH keys and click Add new SSH key.
