### Encrypt private key
AWS generates a private key without any encryption by default, to secure it with a password:
```
$ ssh-keygen -p -f /home/example/.ssh/private_key.pem
Enter new passphrase (empty for no passphrase): ****
Enter same passphrase again: ****
Your identification has been saved with the new passphrase.
```
SSH will prompt for password after this:
```
$ ssh server1
Enter passphrase for key '/home/example/.ssh/private_key.pem': ****
```
## kitty compatibility
If you use [kitty](https://sw.kovidgoyal.net/kitty/index.html) terminal to ssh into your Linux instance, you may find the backspace doesn't work. That is because kitty uses different terminfo.
