SSH keys allow you to login without requiring you to type in your password this tutorial will teach you how to set them up

First we need to create the key
```
ssh-keygen -t rsa
```
Then we need to move it over to the machine that we want to be able to login too without the need for a password to do this run the following command
```
scp .ssh/id_rsa.pub OTHER-MACHINES-IP:.ssh/authorized_keys
```
You should now be able to ssh into that machine without needing a password

Open up /etc/ssh/sshd_config and add the following to the end of it

Subsystem sftp internal-sftp
Match group chrooted
ChrootDirectory /home/%u
X11Forwarding no
ForceCommand internal-sftp

Restart SSHD
```
/etc/init.d/ssh restart
```
Then make users chrooted by adding them to the chrooted group
```
adduser user chrooted
```
Now when the user sftps the server they will only see the contents of there home folder
