+# SSH
+**SSH (Secure Shell)** lets you securely connect to remote computers and run commands. Authentication uses passwords or public-key cryptography. Transfer files securely with `scp` or `rsync`. Tunnel arbitrary traffic through SSH connections for security and access through firewalls.
+SSH is the standard for remote system administration, development on servers, and secure file transfer. Every modern system runs an SSH server. Client tools: `ssh` (connect), `scp` (copy files), `ssh-keygen` (generate keys), `ssh-add` (manage keys).
+```bash
+$ ssh user@host                 # connect to remote host
+$ ssh -i key.pem user@host     # use specific private key
+$ scp file user@host:/path     # copy file to remote
+$ ssh-keygen -t ed25519         # generate key pair
+```
+Public-key authentication is more secure than passwords. Generate a key pair, copy the public key to the server, and SSH uses it for authentication. You can also configure SSH tunneling, jump hosts, and multiplexing for advanced usage.
